◆ constructDofTable()

template<int DisplacementDim>

void ProcessLib::PhaseField::PhaseFieldProcess< DisplacementDim >::constructDofTable ( )

This function is for general cases, in which all equations of the coupled processes have the same number of unknowns. For the general cases with the staggered scheme, all equations of the coupled processes share one DOF table hold by _local_to_global_index_map. Other cases can be considered by overloading this member function in the derived class.
