SOLIDWORKS Flow Simulation - Local Mesh Refinement (Equidistant Meshing) 

Hello, the approach to repair a model depends on its shape. But there is a common goal. It is closing all openings if you run a internal analysis. No opening should be exist on model. You are supposed to have a completely closed internal gap. Sometimes it is easy to find and close openings. Yet, it may be hard other times. It depends on model you work on.

@@NonCADKeys If it is possible, sir, may I request a tutorial on how the model was created and what parameters were set in order to do the simulation?

@@mercygracesomorostro8472 we can arrange something I guess. We can record a video to show basic definitions required for an internal analysis.

@@NonCADKeys Thank you very much, sir; it would be a great help. Alternatively, you could maybe create a written instructional in lieu of the video to avoid taking much of your time. But of course, having it demonstrated to us virtually will also be very beneficial for our studies.

hello any update on this problem? cant seem to run the mesh due to the need of repair stating it is not watertight

Hello, the purpose of the simulation is to calculate drag and lift forces on the wing profile . However, the focus is refinement of mesh using local mesh capabilities.
