Exporting for additional CAD modeling
 
Hi all,

I'm a newbie with this software and I'd like to ask if it's possible to export my region for CAD modeling (I started my work with a .iges file,repaired surfaces,made the mesh,physics,everything and initialized simulation...now I must see the behavior adding rudders).
My version is 4.04 (waiting for the latest one,hopefully only a few days) and I'm looking to export to CATIA,Solidworks and similar softwares.

Thanks in advance.

Well you can always select the Representation you want to be exported (Improted Mesh, Remeshed Surface or an extracted boundary from a Volume Mesh) from Representations and then export it in several formats.

However I'm not sure as to how you can modify these again the the CAD package.

Thanks Aroon,in fact I tried to export those representations but I didn't find a common format for my CAD modeller...

I might not be undserstanding your problem correctly, but why dont you just make the changes in a CAD package and then redo the simulation in CCM+??

The imported part was given to me modelled with Rhinoceros and saved in .iges format...I lost a great amount of time repairing all the surfaces within CCM+ and I didn't want to redo the same (I still have only the .iges file) for the whole hull with a few appendices more.
I solved the problem modelling the appendices with a solid CAD modeller and importing them as new regions, then performing boolean operations.

Try to use the surface wrapper, this will fix your geometry and save your time... Once you imported the geometry, STAR-CCM+ understands it as a "mesh" file. The only format that maybe a CAD can read is .stl. If you get a latest version, like 5.02, you can import it as a geometry in the 3D-CAD modeller, and there make some changes...

Thanks, I tried the 3D-CAD module but I was looking for something more accurate 'cause I needed to model not only rudders but marine propellers too.
Anyway, the most important thing is that my problem's been solved in a way or another...surely I'll try your method in the near future.

Really appreciate your help, guys. ;)
