April 5, 2018 at 3:13 pmbterhuneSubscriberI could use some guidance on trying to do an external flow around some truck CAD I have. The Trailer is solids but the Cab is surface bodies and doesn't map into the Discovery LIVE flow domain. I tried the shrinkwrap tool but it just creates faceted surface geometry which is still not useful for the external flow. Is there a semi-easy way to convert that surface geometry to solids (even close enough type of conversion) so LIVE will solve flow around it?

If they are individual faces that just need to be joined to make a watertight solid cab, you can open the file in Discovery SpaceClaim and use Repair > Stitch. There is also a tool there to fix gaps and another one to replace any missing faces. You can try them in that order to see if you're able to generate solid geometry. You also have the option of using the Pull command to thicken surfaces, but with a model like this some solid bodies may begin to run into others as their thickness is increased, and the program won't like that. Your best option is to try the Repair tools. If you need further assistance please let me know. There are a few videos in the forum knowledge base that go over these tools. I'd recommend watching these 2 to start: https://discoveryforum.ansys.com/t/m2pk2r/spaceclaim-for-model-prep-turbomachinery https://discoveryforum.ansys.com/t/q5pf9z/stitch-faces-split-edges-tools-in-spaceclaim

If you can share your model, I am sure we could upload a video showing some cleanup techniques on it.
