◆ operator()()

MoFEMErrorCode MoFEM::VolumeElementForcesAndSourcesCore::operator() ( )

virtual

Main operator function executed for each loop iteration.

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

Returns: Error code indicating success or failure
