I’ve been trying to use the scene IncisionTriangleProcess.scn in v18.12 branch, but with a smaller mesh I made. But when I run the scene I got this error <[TopologicalChangeProcessor(topologicalChangeProcessor1)] While computing computeIntersectedPointsList between triangles '7' and '9' at time = '3'>
I’ve tried with several coordinates in the .txt file but I still get the same error.
This is the mesh file:
$NOD

And the text file:

T= 10
INCISE= 2
6 5 0 5 5 0
Hi,
Looking only at the numbers. I think you are trying to incisé outside of the mesh.
Do you confirm that you Can see the mesh when you start thé simulation before cutting?
The numbers in the .txt are 3d coords. So your first incision point is on (5,6,0) while your points are between (0,0,0) and (2,2,0).
Let me know if changing thé coords in the txt works.
Regards,
