Ablation of hexahedral mesh

[CherryJGit]

Since the internal tetrahedrons (triangles) are not aesthetically pleasing when the tetrahedral structure is being ablated, I would like to use a hexahedral mesh filled with cubes. However, I found that there are some errors in the SCN file I wrote (the content and errors are listed below). Could you please help me solve this problem? When I tried to test it in RunSofa and clicked "animate", then held down the shift key and the right mouse button to prepare for ablation, it froze after one cube disappeared. I hope to receive some guidance or a new SCN code file.

Hi,

incision is not supported in hexahedral mesh and I don't see how you will be able to mesh a full 3D geometry using Cubes and Quads (except if the final mesh of your project is a 3D cube of course).
I would recommend to stick to the tetrahedral model and apply one of the solution provided in the other discussions.

Best regards,
