Detailed Description

Base class for Output mesh.

Defines common members for Output mesh classes:

OutputMesh represents output mesh with continuous elements
OutputMeshDiscontinuous represents output mesh with discontinuous elements

Making of output meshes and calling of their initialization methods must be execute in correct order, see example:

// Create or get Mesh object
Mesh * my_mesh = ...
// Construct mesh with continuous elements
std::make_shared<OutputMesh> output_mesh = std::make_shared<OutputMesh>(*my_mesh);
// Creates the sub meshes on all processes identical to the computational one.
output_mesh->create_sub_mesh();
// Creates mesh on zero process identical to the computational one.
std::make_shared<OutputMesh> serial_output_mesh = output_mesh->make_serial_master_mesh();
// Construct mesh with discontinuous elements
std::make_shared<OutputMeshDiscontinuous> output_mesh_discont = std::make_shared<OutputMeshDiscontinuous>(*my_mesh);
// Creates sub meshes on all processes mesh from the original my_mesh.
output_mesh_discont->create_sub_mesh();
// Creates mesh on zero process from the original my_mesh.
std::make_shared<OutputMeshDiscontinuous> serial_output_mesh = output_mesh->make_serial_master_mesh();
