function is run at the end of loop

It is used to assembly matrices and vectors, calculating global variables, f.e. total internal energy, ect.

Iterating over dofs: Example1 iterating over dofs in row by name of the field for(IT_GET_FEROW_BY_NAME_DOFS_FOR_LOOP(this,"DISPLACEMENT",it)) { ... }

Reimplemented from MoFEM::BasicMethod.
