Detailed Description

Metadata for a distributed composite vector.

This class describes a vector that contains one or more sub-vectors (see P1bubble arrays), each sub-vector has the same shape as the base vector, plus one dimension if shapes_[i] > 0 See also class DoubleTab_Parts and class ConstDoubleTab_Parts

MD_Vector_composite can be nested (for example when using the U_P solver, where velocity and pressure are gathered in a single vector, and pressure itself has different support entities).

The overall parallel information is aggregated in the member global_md_ which contains the overall equivalent of all the parts.

◆ add_part()

void MD_Vector_composite::add_part	(	const MD_Vector &	part,
		int	shape = 0,
		Nom	name = "" )

Append the "part" descriptor to the composite vector.

By default, shape=0 says that for each item in "part", one item will be appended to the composite descriptor. If shape=n, each items in "part" will be duplicated n times in the composite descriptor. The difference between 0 and 1 is when we create parts with DoubleTab_parts (see class DoubleTab_parts) Exemples: 1) P1Bubble pressure fields have one, two or three parts with shape=1. (see Domaine_VEF::discretiser_suite()) 2) One can create a composite field containing

velocity degrees of freedom at the faces
pressure d.o.f. at the elements
one multiscalar d.o.f at nodes MD_Vector_composite mdc; mdc.add_part(domainevf.md_vector_faces(), dimension); mdc.add_part(domaine.md_vector_elements(), 0 // scalar //); mdc.add_part(domaine.md_vector_sommets(), 1 // multiscalar with 1 component //); MD_Vector md; md.copy(mdc); I will create a DoubleVect of this form by attaching this descriptor: DoubleVect v; MD_Vector_tools::creer_tableau_distribue(md, v); DoubleTab_Parts parts(v); // parts[0] has nb_dim()==2, dimensions are [ domainevf.nb_faces_tot, 3 ] // parts[1] has nb_dim()==1, dimension [ domaine.nb_elem_tot ] // speciel case shape==0 // // parts[2] has nb_dim()==2, dimension [ domaine.nb_som_tot, 1 ] I can duplicate items in the descriptor by creating DoubleTab objects: The following code will create an array containing 12 d.o.f for each face followed by 4 d.o.f for each element and 4 d.o.f for each node: DoubleTab tab(0, 4); MD_Vector_tools::creer_tableau_distribue(md, tab); DoubleTab_Parts parts(tab); // parts[0] has nb_dim()==3, dimensions are [ domainevf.nb_faces_tot, 3, 4 ] // parts[1] has nb_dim()==2, dimension [ domaine.nb_elem_tot, 4 ] // speciel case shape==0 // // parts[2] has nb_dim()==3, dimension [ domaine.nb_som_tot, 1, 4 ]
