Detailed Description

Mesh related input options.

Function Documentation

buildParallelMesh()

std::unique_ptr< mfem::ParMesh > serac::mesh::buildParallelMesh	(	const InputOptions &	options,
		const MPI_Comm	comm = MPI_COMM_WORLD
	)

Constructs an MFEM parallel mesh from a set of input options.

Parameters

[in]	options	The options used to construct the mesh
[in]	comm	The MPI communicator to use with the parallel mesh

Returns

A unique_ptr containing the constructed mesh

refineAndDistribute()

std::unique_ptr< mfem::ParMesh > serac::mesh::refineAndDistribute	(	mfem::Mesh &&	serial_mesh,
		const int	refine_serial = 0,
		const int	refine_parallel = 0,
		const MPI_Comm	comm = MPI_COMM_WORLD
	)

Finalizes a serial mesh into a refined parallel mesh.

Parameters

[in]	serial_mesh	The "base" serial mesh
[in]	refine_serial	The number of serial refinements
[in]	refine_parallel	The number of parallel refinements
[in]	comm	The MPI communicator

Returns

A unique_ptr containing the constructed mesh

Note

It is sometimes required to refine serially first if your number of processors is less than the original number of mesh elements
