When I run the example DEM_14 CaseBowling, I just changed the dimension from 2D to 3D, but the error was as follows. Could you tell me why?

  • can you please try to execute the same case with less particles to check if the error persists?
    can you also to try the same case without using DEM just to see if the problems comes from there?

  • Hello

    I have the same problem. Could you solve it? How did you do it?

    Thank you
