Modeling with ANSYS Mech APDL

[tyler_leon]

Hi all,
I'm a new member of this forum.

My problem is that I'm trying to modelling an underground cavern group using ANSYS APDL starting from a BIM modeler. I'm able to import the IGS file with the geometry (volumes), but I encounter some problems:

My cavern complex is built in BIM using also a "box" representing the ground. How can I make the volumes (and so the mesh) communicate each other? Now I have only some independent volumes… It would be correct to use the boolean operation? If yes, how can I use them?

Thank you very much for the help!

One should be able to do this in APDL using Boolean operations, not done it a lot myself though but I am sure there are lots of tutorials (+documentation).

I would myself bring the CAD in to Designmodeler, which is much more CAD friendly, and do all the Boolean operations there, where one can show and hide volumes in order to see if the common intersections have been achieved between parts. Finally when this is done export that as an IGES file and do the rest of the analysis if needed in APDL.
