Introduction ============ **topIIvol** meshing tool provides sequential/parallel tools for creating volumetric tetrahedral meshes from a given topology (point-cloud `*.xyz`). Running topIIvol Plug-in ======================== **topIIVolMesh** plug-in can be invoked via SMESH Plugin item in Mesh menu bar .. image:: images/callTopIIVolMesh.png :align: center **topIIVolMesh** Options ======================== Sequential mode --------------- If the number of processors is set to 1, **topIIvol_Mesher** sequential tool is called for creating volumetric tetrahedral meshes from a given topology. The volumetric mesh can be displayed in SALOME by ticking the "Display mesh" check-box. The list of input parameters are: - DEM input file: input point cloud file; - Number of X points present in the input point cloud; - Number of Y points present in the input point cloud; - Number of Z points intended in the z direction; - Depth of the mesh needed; - temporary directory for calculation. Parallel mode --------------- If the number of processors is greater than one, **topIIvol_ParMesher** parallel computing tool is called for creating volumetric tetrahedral meshes from a given topology. The volumetric mesh can be displayed in SALOME by ticking the "Display mesh" check-box. The list of input parameters are: - DEM input file: input point cloud file; - Number of X points present in the input point cloud; - Number of Y points present in the input point cloud; - Number of Z points intended in the z direction; - Depth of the mesh needed; - Number of MPI ranks - temporary directory for calculation. Distributed mode ----------------- If the check-box **Distributed** is ticked, **topIIvol_DistMesher** computing tool is called for creating embarassingly parallel distributed meshes from a given topology. The list of input parameters are: - DEM input file: input point cloud file; - Number of X points present in the input point cloud; - Number of Y points present in the input point cloud; - Number of Z points intended in the z direction; - Number of partitions in X direction; - Number of partitions in Y direction; - Number of partitions in Z direction; - Depth of the mesh needed; - Number of MPI ranks - temporary directory for calculation.
