How to create crack on meshed model?

Is there a way to analyze using calculix in the current model by subtracting the nodes and elements determined in the middle of the modal?

I would be pleased if you could help.

You’d just have to create a seam - duplicate the nodes of some elements so that they have the same coordinates but aren’t connected.

Thanks for your answer. May I also ask:

  1. What is the command where I can see the node points and element numbers?
  2. What are the commands required to create a seam?

I don’t know if GraphiX can do it but there’s a plug-in for Gmsh that may help you: GitHub - AlfaBetaBeta/gmsh-crack-generator: gmsh plugin to generate cracks inside 3D FE solid meshes.
