Hello,

I had an object scanned and I have eventually ended with an STL file of the scanned object. This geometry is composed of many triangles and, as it is normal, it is not smooth at all.

When I try to generate a mesh for CFD, I can not generate a mesh that is well enough, and when I simulate the case, I see that in a couple of areas there are a few elements that have abnormal values for the velocity. This is clearly because of the mesh. I tried to refine it, or employ some methods such as inflation to the walls, but it could not create a mesh, I suppose due to the large number of triangles that describe the surface.

So, the question is this; Is there a way that I can approach this kind of situation to generate a mesh that is good?

Sorry for the vagueness of the question, if anybody can help, I will be happy to share the specifics that are needed.
Thank you!!

Open the STL file in SpaceClaim and get on the Facet tab where there are tools that can smooth out the surface.

Watch some of the videos I have recorded.

Thank you very much!
It was a really helpful series of videos.
