Hi all, I am facing some problems during the mesh creation. The geometry has been created in OnShape and exported as a STEP. The fact is that since July I have been working with a geometry created with the same procedure without any problem, but now I did some minor modifications on the geometry an…

Hi @alex_roque , I am trying to identify the cause but could not find anything so far. If I am not mistaken you could use feature scripts on Onshape to check your geometry but I never tried it tbh. Darren ( @1318980 ), do you know if these scripts also work for FEA because for CFD they do for sure. I…

Hi @jousefm @alex_roque , yer feature scripts can do pretty much whatever you want them to do, but beware, because they are features you could create a script that says, queries all small faces, a large geometry will take ages, potentially time out and will do the operation upon every re-generation,…

Hi @alex_roque , there seems to be some issue with the refinement you have chosen. When removing every refinement I get a coarse mesh without any error messages. I will try to increasingly refine the mesh later on and let you know about my progress. Best, Jousef

Hi @jousefm , thanks to your information I developed some tests reaching the same results as you, that is to say, by removing all the refinements I can get a mesh no matter what geometry I use. Which is not very useful since I need the refinements. After that I carried out some other tests so as to …

Hi @alex_roque ! Exactly what I experienced as well with the refinement ON/OFF approach. @yosukegb4 , can you see if there is some kind of overlap or corrupted component with Rhino? Unfortunately I did not manage to get a tool on my machine so far (shame on me) to check weird behavior of CAD models. …

Hi Darren ( @1318980 ), Can you tell me where I can find this feature script you talk about? I am looking for it right now but I can’t find it! Thanks in advance. Alex

Hi @alex_roque , I think we found the issue. I just filed a bug report. There is indeed an issue with refinements on Tet-Dominant meshes with newly uploaded geometries (where we would use our new CAD kernel). I will let you know as soon as I have any updates. PS: To unblock you, if you like, I can…

Hi Richard, Thanks for the feedback. It would be nice if you could upload my geometries with the old kernel, how can we do it? How can I send you the geometries so that you can upload them?

Hi @alex_roque , no need to send me the geometries they are already uploaded to the project. If not please just upload them. I would only need the names of the geometries which you would need to be re-imported. Best, Richard

Ok, the geometries I need are the last 3 that I just uploaded, the ones finished with _r2

Hi @jprobst,

I just tried it and it works perfectly! Thanks for the quick solution!
