Smoothing the surface
2 Attachment(s)
Dear all,
I am working with sHM a long time but I never solved the following problem! If I am using multi-region cases I got bad surface approximation on curved surfaces (see the attached pictures). If I mesh just one region - everything is fine. Does someone know any solutions for this? I think this depend on the multi-domain function of sHM. Maybe it happend after splitting the mesh?! Regards Tobi |
But can you exactly post what is the problem? Wasn't able to figure out it from the pictures you've attached.

Hi, the problem - maybe its not a problem - is that the surface is not smooth enough. If I just mesh the cup region then I get a extreme accurate surface approximation. If I am home again I will do this again and post a new picture so that the differences are clear. To clear it up: - one region: accurate and smooth surface - multi region: no smooth surface (see pictures) - snatchy surface. Regards Tobi |

Okay.
In the attachment you find the surfaces after meshing but just the cup (no multidomain with cellZones and faceZones). The question now. Is it possible to get such a surface with the multidomain meshing too or not? Regards Tobi |
I do not know where these issues come from, but I was able to fix it by trying different mesh settings.
You have to play with the values: nSolveIter, nRelaxIter, nFeatureSnapIter. explicitFeatureSnap true and multiRegionFeatureSnap false did a better job for me than implicitFeatureSnap. Furthermore the meshQualityControls may have an influence on the result. As a starting point you may use my settings: Code:
snapControls Code:

Hi,
I will check it out. I used explizit Feature snapping and have more iterations on smoothing as you mentioned but I will check you Settings. It only appears with multi-Region! |
Hello Tobi,
Have you figured out something to smooth surface while using SHM for multiregion meshing? I have seen your tutorials on your website for mutiregion meshing. In those tutorials, surface is not smooth. Did you face any problem in simulation due to non-smooth surface? Thank you Regards |
