In ``parallel``, an example of how to run a 2D parallel simulation is presented.
First, the mesh needs to be distributed among the processors. This is done with::
const auto & comm = Communicator::getStaticCommunicator();
Int prank = comm.whoAmI();
if (prank == 0) {
mesh.read("square_2d.msh");
}
mesh.distribute();
Here ``prank`` designate the processor rank. The mesh is read only by processor 0 and then distributed among all the processors.
All the prints are done only by processor 0. For instance::
if (prank == 0) {
std::cout << model.getMaterial(0) << std::endl;
}
.. figure:: examples/c++/solid_mechanics_model/parallel/images/parallel.png
:align: center
:width: 60%
Displacement in the x direction.
