I am doing the Incompressible Flow analysis. However, when I am modifying the mesh, it tells me to enclose the model and delete the mesh inside the model as I selected to modify the inside mesh.
this is the error information it provided for me, somebody know how to fix it?
The flow region could not be created due to the following problematic entities: face947187@solid1998. Please consider cleanup operations in your CAD tool.
Hi!
I copied your project and tried to create the enclosure in the CAD Edit mode, because the old operations are being deprecated.
Anyways, the operation also failed. I couldn’t pinpoint the exact issue, but most probably there is a gap in your model, a very small face or an intersection that can not be resolved properly. For example, I couldn’t fuse all the parts.
I would say that you need to try and clean the model in your CAD program. You can also try to create the enclosure there.
Also, please be aware that such a big domain might not be practical to simulate, so consider to reduce it.
