I have imported the geometry for a conjugate multiphase flow-heat exchange simulation project and found that only the STEP file reported been watertight and having shells. But, this STEP file reported having an error: “Geometry import reported body check errors. In case you face issues in meshing consider cleanup operations in your CAD tool”. I don’t know what this error might be.
On the other hand, the IGES and PARASOLID didn’t report errors but didn’t report watertight feature and shell presence neither.
To do the meshing and simulation, which format should I choose?
I attach an image of the data of event log for the 3 formats.
Thank you in advance!!!
