Dear SimScale Team, since some days I try to mesh a vehicle geometry for a aerodynamics simulation based on data of a project from our past. First I tried to mesh the full geometry inclusive rough engine room components and a radiator dummy to take the flows through the geometry into account. See …

The fact that you were able to mesh properly with dummy geometry confirms that your procedure is correct and the issue lays in the geometry. Would you consider sharing the geometry? If not, how about the subtraction approach that I suggested? Its not the same process but it should be able to provide…

Hi @jjanczyk given that your project is private it is hard to see what went wrong. Are those finer meshes regions you purposely defined? Is your material point clearly outside (or inside) as it is supposed to? To be completely honest, I believe that the error is your geometry. You have the right app…

Hi @oscarcorripio , thanks for your reply. I checked the stp file different times with two different CAD tools (CATIA V5 and Geomagic Design X). I converted the file from .CatPart to .stp and read it back into the tools. Result in both tools was a 1 piece solid as it also written in the simscale ge…

Hi @oscarcorripio , thank you very much for your tips. I have generated the volume of the basemeshbox wihout the car body but did not load it up to my simscale account for the reason I tested a little bit with stl - files which is much better with this complexity than to use step - data. Simscale ru…

Difficult meshing of geometry. Issue: Mesh at in and outside of the body (car) in despite of watertight geometry
