auto test_bit_child
Initial value:
= [](FEMethod *fe_ptr) {
return fe_ptr->numeredEntFiniteElementPtr->getBitRefLevel().test(
nb_ref_levels);

lambda function used to select elements on which finite element pipelines are executed.

Note
childs elements on pipeline, retrieve data from parents using operators pushed by set_parent_dofs
