Reconstruct Aspherix Bodies

Merge Aspherix bodies into OVITO particles

Description

The Aspherix DEM software can output concave particles as bodies composed of multiple convex sub-particles. OVITO can read this body information into a DataTable. This modifier can be used to post-process the data table and replace the convex sub-particles in the DataCollection with their concave counterparts.

Note: This modifier currently only works for mesh based particles. If you require multi-sphere particles please open a GitHub issue.

Parameters

GUI name	Python name	Description	Default Value
Static color	body_color	Single solid color applied to each newly created particle.	(255 / 255, 102 / 255, 102 / 255)
Random colors	random_color	Apply a random color to each unique body.	False
Delete sub-particles	delete_sub_particles	Delete the sub-particles originally found in the DataCollection.	True

Example

Seperate sub-particles after a normal file import:
