[ANSYS Meshing] problem meshing a missile

behzadjabbari68@gmail.com · November 8, 2015, 11:48

Hi, I want to simulate flow over a missile importing that from solidwork to gambit.
This missile includes some volumes : main part, front wings, back wings.
I can't operate boolean operations to unite these volumes and then subtract missile from the domain to have a single volume, becasue there is virtual volume in the importing geometry from solidwork.
How can I have a single volume in spite of the fact that there are real and virtual volumes in the geometry??

As you mentionned you cannot perform boolean operations since you have virtual geometry.
Do you have the possiblity to extract fluid volume in solidworks?
What kind of format did you import in gambit?

I solved this problem .I imported the solid file in the parasolid format.Now i have one volume and want to mesh it.
What is your advise for meshing such a complex volume?
