no intersection nodes found Answered

Hi onscale team.


I'm trying to run my 3D model but it cannot.


Error message is shown as following;


 **** PZFlex  has detected an error****
     ****Subroutines tracked are: intsect_grid          pizinp                jobctl                flex                
     ****Error occurred in subroutine intsect_grid          ****
     ****Error message****
     no intersection nodes found


How can I fix it?


Many thanks.

  • This can happen when trying to define an interface between materials and the routine fails to find nodes at the interface. For example when a CAD part is smaller than the mesh and is therefore not represented in the grid. A way to address this is to use keypoints in your grid definition. Alternatively, you can reduce the size of your mesh, which can increase the possibility of the nodes being present.

    Let me know if this does not resolve your issue.

  • Sorry for the late reply.

    In the 3D model, is it possible to set the key points as curved shapes?

    I am getting an error with the attached model.

    The mesh is set up as wavelength based.
    Since the CAD is large, I don't think it is possible for the nodes to not exist.

    Please help me.
