◆ VerifyDefinedBoundaries()

void mfem::spde::Boundary::VerifyDefinedBoundaries ( const Mesh & mesh ) const

Verify that all defined boundaries are actually defined on the mesh, i.e. if the keys of boundary attributes appear in the boundary attributes of the mesh.

Verify if all boundary attributes appear as keys in the boundary attributes, if not let the user know that we use Neumann by default.

Check if any periodic boundary is registered
