PenaltyInclinedNoDisplacementBC

Penalty Enforcement of an inclined boundary condition

Description

PenaltyInclinedNoDisplacementBC is a IntegratedBC used for enforcing inclined boundary conditions unormal=0\mathbf{u}\cdot \mathbf{normal} = 0 for mechanics problems. With a penalty method, the residual is given as Ri=α(unormal)normal(component)ψi\mathcal{R}_i = \alpha(\mathbf{u}\cdot \mathbf{normal})\mathbf{normal}(\text{component})\psi_i where α\alpha is the penalty parameter and component corresponds to the direction in which to apply the residual. The normal directly comes from the surface normal defined in a mesh.
