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.

Get the size and the sparse pattern of the global matrix in order to create the global matrices and vectors for the system equations of this process.

Parameters

process_id

Process ID. If the monolithic scheme is applied, process_id = 0. For the staggered scheme, process_id = 0 represents the hydraulic (H) process, while process_id = 1 represents the mechanical (M) process.

Returns
