Introduction

Minimum System Requirements

In general, the following is required for MOOSE-based development:

A POSIX compliant Unix-like operating system. This includes any modern Linux-based operating system (e.g., Ubuntu, Fedora, Rocky, etc.), or a Macintosh machine running either of the last two MacOS releases.

System Purpose

The purpose of Cardinal is to perform fully integrated, high-fidelity, multiphysics simulations of nuclear energy systems at high-fidelity with a variety of materials, system configurations, and component designs in order to better understand system performance. Cardinal's main goal is to bring together the combined multiphysics capabilities of the MOOSE ecosystem with leading high-performance tools for radiation transport (OpenMC) and Navier-Stokes fluid flow (NekRS) in an open platform for research, safety assessment, engineering, and design studies of nuclear energy systems.

System Scope

Cardinal is an application for performing high-fidelity simulation of nuclear systems incorporating Monte Carlo neutron-photon transport and/or spectral element CFD. These physics can be combined with one another and with the MOOSE modules to accomplish "multiphysics" simulation. High-fidelity simulations can also be performed independently, for the purpose of data postprocessing, to generate constitutive models suitable for lower-fidelity tools, a process referred to as "multiscale" simulation.

Interfaces to other MOOSE-based codes, including systems-level thermal-hydraulics (SAM), heat pipe flows (Sockeye), and fuel performance (Bison) are also optionally included to support Cardinal simulations. Cardinal enables high-fidelity modeling of heat transfer, fluid flow, passive scalar transport, fluid-structure interaction, nuclear heating, tritium breeding, shielding effectiveness, material activation, material damage, and sensor response. The MultiApp System is leveraged to allow for the multiscale, multiphysics coupling. Further, other MOOSE capabilities in the modules, such as the Stochastic Tools Module enable engineering studies with uncertainty quantification and sensitivity analysis. Cardinal therefore supports design, safety, engineering, and research projects.

Assumptions and Dependencies

The Cardinal application is developed using MOOSE and is based on various modules, as such the RTM for Cardinal is dependent upon the files listed at the beginning of this document.

Pre-test Instructions/Environment/Setup

Ideally all testing should be performed on a clean test machine following one of the supported configurations setup by the test system engineer. Testing may be performed on local workstations and cluster systems containing supported operating systems.

The repository should be clean prior to building and testing. When using "git" this can be done by doing a force clean in the main repository and each one of the submodules:

git clean -xfd
git submodule foreach 'git clean -xfd'

All tests must pass in accordance with the type of test being performed. This list can be found in the Software Test Plan.

cardinal: Cht
1.3.1The system shall correctly evaluate volume postprocessors for a dimensional NekRS solve on a conjugate heat transfer mesh. We test this by repeating the same integrals of the mapped data on the MOOSE mesh, and show exact equivalence.
Specification(s): volume_pp
Collection(s): FUNCTIONAL
Type(s): CSVDiff
1.3.2A coupled MOOSE-nekRS pincell-fluid flow problem shall predict correct conservation of energy and realistic thermal solutions when nekRS is run in nondimensional form. A wide variety of postprocessors are measured and compared against the same problem in dimensional form in the ../sfr_pincell directory. Most measurements match exactly, but there is about a 0.1% difference in temperatures (this is to be expected, though, because the _solve_ is not exactly the same between a nondimensional and dimensional case - the governing equation is the same, but not necessarily the number of iterations, etc.
Specification(s): sfr_pincell
Collection(s): FUNCTIONAL
Type(s): Exodiff
1.3.3A coupled MOOSE-nekRS pincell-fluid flow problem shall predict correct conservation of energy and realistic thermal solutions when nekRS is run in nondimensional form using an exact mesh mirror. This solution was compared to the sfr_pincell case, and results are very similar with only small differences due to the different mesh mirror representations. The usrwrk_output feature was also used to check the correctness of the flux map into NekRS.
Specification(s): sfr_pincell_exact
Collection(s): FUNCTIONAL
Type(s): CSVDiff
1.3.4A coupled MOOSE-nekRS pebble flow problem shall predict physically realistic conjugate heat transfer when using an initial offset in the scratch space. The gold file was created when using no offset to prove equivalence.
Specification(s): pebble

1.3.5A coupled MOOSE-nekRS pebble flow problem shall predict physically realistic conjugate heat transfer.

Specification(s): output_cht
Collection(s): FUNCTIONAL
Type(s): RunApp
1.3.7A coupled MOOSE-nekRS pincell-fluid flow problem shall predict correct conservation of energy and realistic thermal solutions. Exact conservation of energy (based on the power imposed in the solid) will not be observed because some heat flux GLL points are also on Dirichlet boundaries, which win in boundary condition ties.
Specification(s): sfr_pincell
Design: NekRSProblem
Collection(s): FUNCTIONAL
Type(s): Exodiff
1.3.8Individually conserving heat flux sideset by sideset shall give equivalent results to the all-combined option when there is just one coupling sideset. The gold file for this test is identical to that for the sfr_pincell case.
Specification(s): sfr_pincell_vpp
Design: NekRSProblem
Collection(s): FUNCTIONAL
Type(s): Exodiff
1.3.9The system shall allow imposing heat flux through a dummy main application, instead of coupling NekRS via conjugate heat transfer. This is verified by computing the heat flux on the NekRS mesh, which adequately matches an initial value set in a postprocessor. This gold file is also identical to that obtained by running a dummy main app (solid_dummy) that passes in the desired flux_integral initial condition.
Specification(s): impose_heat_flux
Design: NekRSProblem
Issue(s): #797
Collection(s): FUNCTIONAL
Type(s): CSVDiff

cardinal: Conduction
1.4.1A coupled MOOSE-nekRS heat conduction problem shall produce the correct temperature distribution when (1) a heat source is applied in the nekRS volume and (2) a heat flux is imposed in nekRS through a boundary. The same problem is created in a standalone MOOSE simulation, in moose.i. Temperatures agree to within 0.2% degrees, and the agreement can be made better by using finer meshes in the coupled Cardinal case.
Specification(s): pyramid
Collection(s): FUNCTIONAL
Type(s): Exodiff
1.4.2The system shall couple NekRS to MOOSE through simultaneous boundary heat flux and volumetric heating when using an exact mesh mirror. The solution is nearly identical to the pyramid test and the usrwrk output for flux and volumetric heating match the auxiliary variables in the Nek-wrapped input.
Specification(s): pyramid_exact
Collection(s): FUNCTIONAL
Type(s): CSVDiff
1.4.3The system shall error if the user specifies a duplicate variable with a name overlapping with special names reserved for Cardinal data transfers.
Specification(s): duplicate_temp
Collection(s): FUNCTIONALFAILURE_ANALYSIS
Type(s): RunException
1.4.4A coupled MOOSE-nekRS slab heat conduction problem shall predict the correct interface and volume temperatures based on an analytic solution. The MOOSE portion of the domain (the left half) is compared against an exodiff with this test, while the nekRS portion of the domain (the right half) has been compared off-line at the time of the generation of this test to the known analytic solution via line plot in Paraview (this has to be done offline because the 'visnek' script needs to be run to get the nekRS output results into the exodus format. A heat conduction simulation performed with MOOSE over the combined nekRS-MOOSE domain in the 'moose.i' input file also matches the coupled results very well.
Specification(s): slab_conduction
Collection(s): FUNCTIONAL
Type(s): Exodiff
1.4.5A coupled MOOSE-nekRS two-region pyramid heat conduction problem shall predict the correct interface and volume temperatures that are obtained from a standalone MOOSE heat conduction simulation in the moose.i file of both pyramid blocks. Because only a constant heat flux is passed for each element during the data transfer from MOOSE to nekRS, we do not expect the results to match perfectly with the MOOSE standalone case (which represents the heat flux internally as a continuous function (as opposed to elementwise-constant). We compare extrema temperature values on the two pyramid blocks with the MOOSE solution, and see that (1) the overall temperature distribution matches qualitatively, and (2) the difference between the Cardinal case and the MOOSE standalone case decreases as the mesh is refined (i.e. as the effect of the constant monomial surface heat flux is lowered). Even with the fairly coarse mesh used in this test, the errors in temperature are less than 1% of the total temperature range in the problem (but can locally be high relative differences).
Specification(s): pyramid_conduction
Collection(s): FUNCTIONAL
Type(s): Exodiff
1.4.6A coupled MOOSE-nekRS slab heat conduction problem shall produce the correct temperature distribution when a heat source is applied to the nekRS problem. A reference MOOSE standalone problem (in moose.i) solves the equation k*nabla(T)7*T, i.e. the 'heat source' is 7*T. This surrogate problem is then repeated with Cardinal, where nekRS solves the k*nabla(T)q, where q is a heat source 'computed' by MOOSE to be 7*T_n, where T_n is the temperature from nekRS. This problem does not really represent any interesting physical case, but is solely intended to show that nekRS correctly solves the heat equation with a heat source 'computed' by some other app. The solution matches the standalone MOOSE case very well - with a nekRS mesh of 15x15x15 elements, postprocessors for the side- and volume-averaged temperature, as well as maximum temperature, match the MOOSE standalone case to within 0.1%. To keep the gold files small here, this test is only performed on a 10x10x10 nekRS mesh.
Specification(s): slab_heat_source
Collection(s): FUNCTIONAL
Type(s): Exodiff
1.4.7A coupled MOOSE-nekRS two-region cylinder heat conduction problem shall predict the correct interface and volume temperatures that are obtained from a standalone MOOSE heat conduction simulation in the moose.i file of both cylinders. Because only a constant heat flux is passed for each element during the data transfer from MOOSE to nekRS, we do not expect the results to match perfectly with the MOOSE standalone case (which represents the heat flux internally as a continuous function (as opposed to elementwise-constant). We compare extrema temperature values on the two cylinders with the MOOSE solution, and see that (1) the overall temperature distribution matches qualitatively, and (2) the difference between the Cardinal case and the MOOSE standalone case decreases as the mesh is refined (i.e. as the effect of the constant monomial surface heat flux is lowered). Even with the fairly coarse mesh used in this test, the errors in temperature are less than 0.5%.As the BISON mesh is refined, the error continually decreases until the temperatures are very close to those predicted by the standalone MOOSE case.
Specification(s): cylinder_conduction
Collection(s): FUNCTIONAL
Type(s): Exodiff
1.4.8The same solution shall be obtained as the cylinder_conduction case when nekRS is run with a smaller time step than MOOSE with subcycling. The run will not require the the same overall number of time steps as the cylinder_conduction test, so we just compare some postprocessor values at the end of the simulation. These CSV results are less than 1e-3 different from those for the cylinder_conduction case, so the simulation process is equivalent. We don't use exactly the same CSV gold file because the number of time steps differs, and would trigger a failure.
Specification(s): cylinder_conduction_subcycle
Collection(s): FUNCTIONAL
Type(s): CSVDiff
1.4.9The same solution shall be obtained when nekRS is run before MOOSE. We compare CSV results against those for the cylinder_conduction case, which match wo within 1e-5. We don't use exactly the same CSV gold file because the number of time steps differ, and would trigger a failure.
Specification(s): cylinder_conduction_reversed
Collection(s): FUNCTIONAL
Type(s): CSVDiff
1.4.10The same solution shall be obtained when nekRS is run as a sub-app with minimized transfers for in the incoming and outgoing data transfers. We compare against the same CSV file used for the cylinder_conduction_subcycle case because the results should be exactly the same.
Specification(s): cylinder_conduction_mini
Collection(s): FUNCTIONAL
Type(s): CSVDiff
1.4.11The system shall support an exact NekRS mesh mirror. The solution is compared against the cylinder_conduction case and nearly identical solutions are obtained.

Collection(s): FUNCTIONAL
Type(s): CSVDiff
1.4.12A coupled MOOSE-nekRS cylinder heat conduction problem shall produce the correct temperature distribution when a heat source is applied to the nekRS problem, and when the meshes do not perfectly line up (i.e. the volumes are different). A reference MOOSE standalone problem (in moose.i) solves the equation k*nabla(T)7*T, i.e. the 'heat source' is f(T,x,z). This surrogate problem is then repeated with Cardinal, where nekRS solves the k*nabla(T)q, where q is a heat source 'computed' by MOOSE to be f(T_n,x,z), where T_n is the temperature from nekRS. This problem does not really represent any interesting physical case, but is solely intended to show that nekRS correctly solves the heat equation with a heat source 'computed' by some other app. The solution matches the standalone MOOSE case very well - postprocessors for the volume-averaged and maximum temperature match the MOOSE standalone case to within 0.1%.

1.4.13The system shall couple NekRS to MOOSE through volumetric heating when using an exact mesh mirror. The output file was compared against the cylinder_heat_source test, giving very similar answers. The heat source sent into NekRS was also checked with the usrwrk_output feature.

Prerequisite(s): 1.4.12 1.4.14
1.4.14A coupled MOOSE-nekRS cylinder heat conduction problem shall produce the correct temperature distribution when a heat source is applied to the nekRS problem, and the nekRS solve is conducted in nondimensional scales. Temperatures match to within 0.1% between the nondimensional version and the dimensional version in ../cylinder.

cardinal: Deformation
1.6.1A boundary displacement in the main app will displace the mesh in NekRS when using a boundary mesh mirror. The deformation is verified by looking at the change in area on the (i) main app, (ii) mesh mirror, and (iii) internal NekRS meshes, which agree very well. Improved agreement is obtained by decreasing the time step of the data transfers, due to the first-order finite difference approximation made for velocity.

1.6.3The system shall be able to run the mv_cyl NekRS example with a thin wrapper when using a volume mesh mirror. We show that the volume and area on the NekRS side is changing, whereas the volume/area in MOOSE will not change because we currently do not send displacements from NekRS to MOOSE.

1.6.5This test solves the steady state heat conduction equation with a source term of 3*sin(x)sin(y)sin(z) and a conductivityof 1. The temperature obtained should be sin(x)sin(y)sin(z).The domain is a cube that is deforming at eachtime step in the to the arbitrary functions t*x*z*(2-z)0.1 for x-coordinates,tx*z*(2-z)0.05 in y coordinates, and t(y+1)(y-1)0.1 in z coordinates.The gold solution was verified by comparing itto the analytic solution and a solution obtained by MOOSE's heat conduction solve.

1.6.6An arbitrary mesh displacement in the main app will displace the meshin the sub-app equivalently at each time-step. This shall be verified bycomparing the areas of each sideset in both the main and the sub-app.The domain is a cube, with the initial area of each of thesidesets being 4.0. The areas across the main and sub-app should matchexactly, provided we are using Gauss Lobatto quadrature for MOOSE's areapost-processors, in order to match NekRS's GLL quadrature.
