Modeling with ANSYS Mech APDL

Modeling with ANSYS Mech APDL

Modeling with ANSYS Mech APDL

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!

RE: Modeling with ANSYS Mech APDL

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.

eBook - Rethink Your PLM
A lot has changed since the 90s. You don't surf the Web using dial-up anymore, so why are you still using a legacy PLM solution that's blocking your ability to innovate? To develop and launch products today, you need a flexible, cloud-based PLM, not a solution that's stuck in the past. Download Now
White Paper - Using Virtualization for IVI and AUTOSAR Consolidation on an ECU
Current approaches used to tackle the complexities of a vehicle’s electrical and electronics (E/E) architecture are both cost prohibitive and lacking in performance. Utilizing virtualization in automotive software architecture provides a better approach. This can be achieved by encapsulating different heterogeneous automotive platforms inside virtual machines running on the same hardware. Download Now
White Paper - The Criticality of the E/E Architecture
Modern vehicles are highly sophisticated systems incorporating electrical, electronic, software and mechanical components. Mechanical systems are giving way to advanced software and electronic devices, driving automakers to innovate and differentiate their vehicles via the electric and electronic (E/E) architecture. As the pace of change accelerates, automotive companies need to evolve their development processes to deliver and maximize the value of these architectures. Download Now
