I'm sticked by the way to get the useful facet of the geogemtry.
The STL file consists of many triangles, and I can't get the polygon like the test geogemtry which I turly want to use as a pump or desorption from this kind of file.
What sofewares I have tried include Autodesk Inventor, Geomagic studio and Imageware. The result makes me exhausted, and I still don't find a good way to deal with this problem.
Can anyone tell me which software you used to get useful STL file from the initial model, I will really apperaciate it.
- Coplanar triangles can be collapsed to polygons when you open an STL file
The test geometry was modeled as a solid body, therefore its borders become a single surface in Molflow.
If you have an existing geometry as a CAD model, then you can either import it to Molflow as is, then use Smart select to delete unnecessary layers (since each wall will consist of two surfaces).
Better yet, remove vacuumwise unrelated components (screws, mechanical supports, etc) from the geometry before importing it to Molflow, or even create from scratch the vacuum part of the real element as a solid body (i.e. "inside out"). This process is definitely hard, at CERN this is often the part of the modeling we spend the most time with. I personally use Autodesk Inventor.
