This is a model of a stiffened plate girder. The APDL code is provided below for its geometry generation. It is not getting meshed after gluing all the volumes. If the volume is subdivided in the intersection locations of the different volumes, then it can be meshed I think after gluing. But dividing them into small volumes in the intersection locations is a tedious process. How to do this in a simplified way?
