Hi everyone!
In my experience, this meshing problem occurs when converting a strongly curved surfece (like cylinder) to STL mesh.
On the other hand, CAD files like STP and IGES did not work well on SimScale CFD meshing for my projects.
So I use STL files for CFD meshing that exported from CAD with adjusting parameters.
I often adjust the parameters as below when this kind of problem occurs.
- Maximum edge length : smaller
- Maximum distance, edge to surface : smaller
( I use Rhinoceros for surface modeling, and I do not know how they provided in your CAD (solidworks?), Sorry. )
If the STL file does not improve even if adjusting the export parameters,
I divide those surfaces on my CAD so that the influences of the of surface curves will be less.
This may not be the ideal answer because it is not a method to solve it on SimScale alone.
Best,
Yosuke
