Reply To: Some questions about * IGA keywords and Nurbs 3D

[Ming han Jia]

Thank you very much for your help. In the process of static compression simulation of entities using the *IGA keyword, I still encounter the following problem. I hope you can give me some help:

This k file ends normally in LS-RUN, but when I open the K file after running, the problem shown above appears. Some points where boundary conditions were applied could not be found. What is the reason for this problem? In the first picture below, we want to impose a fixed support constraint on the point set, and the second picture is the situation where some points are lost after running.Is this situation caused by setting parameters incorrectly during the refinement process?Thanks!
