◆ preProcess()

MoFEMErrorCode DirichletDisplacementBc::preProcess ( )

virtual

function is run at the beginning of loop

It is used to zeroing matrices and vectors, calculation of shape functions on reference element, preprocessing boundary conditions, etc.

Reimplemented from MoFEM::BasicMethod.

Reimplemented in DirichletDisplacementRemoveDofsBc, and DirichletFixFieldAtEntitiesBc.
