pyopensn.mesh.SplitFileMeshGenerator

class pyopensn.mesh.SplitFileMeshGenerator

Split file mesh generator.

Wrapper of opensn::SplitFileMeshGenerator.

Generates the mesh only on rank 0. After partitioning, the mesh is not broadcast to other ranks; instead, a binary mesh file for each is written .

Final execution step.

__init__(self: pyopensn.mesh.SplitFileMeshGenerator, **kwargs) → None

Construct a split-file mesh generator.

Parameters:

  • scale (float, default=1.0) – Uniform scale to apply to the mesh after reading.

  • inputs (List[pyopensn.mesh.MeshGenerator], default=[]) – A list of MeshGenerator objects.

  • partitioner (pyopensn.mesh.GraphPartitioner, default=None) – Handle to a GraphPartitioner object to use for parallel partitioning. This will default to PETScGraphPartitioner with a “parmetis” setting.

  • replicated_mesh (bool, default=False) – Flag, when set, makes the mesh appear in full fidelity on each process.

  • num_partitions (int, default=0) – The number of partitions to generate. If zero, it will default to the number of MPI processes. Automatically ignored if the number of MPI processes greater 1.

  • split_mesh_dir_path (str, default='split_mesh') – Path of the directory to be created for containing the split meshes.

  • file_prefix (str, default='') – Prefix to use for all split mesh files. If not provided, it default to the input path’s folder.

  • read_only (bool, default=False) – Controls whether the split mesh is recreated or just read.

  • verbosity_level (int, default=1) – Verbosity level. 1 will report each 10% complete. 2 will print each part and the number of local cells it wrote.
