operator()()

MoFEMErrorCode FaceElementForcesAndSourcesCore::operator() ( )

virtual

Main operator function executed for each loop iteration.

This virtual function is called for every item (finite element, entity, etc.) in the loop. It is the core computation function typically used for:

• Calculating element local matrices and vectors
• Assembling contributions to global system
• Element-level post-processing operations

Returns
