Hello Plaxis team,I have been facing the trouble about regenerate the Mesh. In my case, I want to make a surface by connecting polycurves (Image below). But when I'm trying to regenerate the mesh and change the coarseness factor, It didn't work and show "Fatal: Could not generate mesh". Would you like to help me about this problem? Because I have been trying for 4 days now and follow your tutorial on youtube but still didn't work in my case.Thank you
