assign_mesh_regions
Last update: 02.04.2026VolumeMeshTool.assign_mesh_regions(target_part_id, target_cell_zonelets, source_part_ids, small_regions_volume_fraction)
Assigns a region id to the cells in target cell zonelets of target part id. The region id is based on their location within source part ids.
Parameters:
target_part_id
Id of the target part.
target_cell_zonelets
Ids of cell zonelets to be split into regions.
source_part_ids
Ids of solids used as a reference for assigning regions.
small_regions_volume_fraction
Regions with volumes smaller than a specified fraction of the total volume are merged into their largest adjacent region. This helps to eliminate isolated cells and thin regions from the output.
Returns:
Returns the VolumeMeshToolResults.
Return type:
Notes
This is a beta API. The behavior and implementation may change in future.
