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 link below:
Unfortunately it was not possible to mesh the geometry. In meshing tree there was signed that operation was ready for calculation. After I started the operation it looks like that process was running. For that reason I changed to dashboard and saw that just started meshing operation was ended with error. After I saw that I changed to the project and saw the status: “operation not ready”. I tried to start the meshing some times again. Every time with same result.
Than I changed the geometry to a less komplex CAD model without engine componets, open engine room and radiator channel. Unfortunately I did get the same result. But at my last try (I changed nothing) the process started correctly end ended up with a mesh. But at the mesh there was another issue: The geometry was meshed in and outside (Cad file was signed as watertight).
With these result I checked if there was a dimension problem in x-z plane. But it was nothing to find.
To avoid a problem in x-z plane (y=0) I extruted my CAD model a little bit in positive y direction for the reason I only use a half of the geometry. With that I was sure that x-z plane (symmetry plane of the _BaseMeshBox) cuts the model.
With these geometry I tried meshing again and again and again. But I got same errors as described above till I got a process which started succesful.
The end result of the succesfull meshing operation was a mesh which was in and ouside again. I can´t self explain why that happend for the reason I did work with a water tight geometry.
Attached the screenshots of the watertight geometry plus the mesh:
Can anybody help?
Thanks a lot.
