Detailed Description

Function Documentation

t8_cmesh_from_msh_file()

t8_cmesh_t t8_cmesh_from_msh_file	(	const char *	fileprefix,
		int	partition,
		sc_MPI_Comm	comm,
		int	dim,
		int	master,
		int	use_occ_geometry
	)

Read a .msh file and create a cmesh from it.

Parameters

[in]	fileprefix	The prefix of the mesh file. The file fileprefix.msh is read.
[in]	partition	If true the file is only opened on one process specified by the master argument and saved as a partitioned cmesh where each other process does not have any trees.
[in]	comm	The MPI communicator with which the cmesh is to be committed.
[in]	dim	The dimension to read from the .msh files. The .msh format can store several dimensions of the mesh and therefore the dimension to read has to be set manually.
[in]	master	If partition is true, a valid MPI rank that will read the file and store all the trees alone.
[in]	use_occ_geometry	Read the parameters of a parametric msh file and use the occ geometry.

Returns

A committed cmesh holding the mesh of dimension dim in the specified .msh file.
