Stl Model and Model after preprocessor are not the same !!!
I 'm try to learning flow-3D.
I modeled like a flow from weir.
And I found problem.
After I did preprocessor the solid model has been changed.
Somes wall of them disappeared. And I tried to run simulation.
And the result showed that there was no that wall.
Please see picture for more detail.
Could anyone guide me what I have done wrong......
Thank in Advance
I believe the wall presented here is a thin wall right? so, I suspect your mesh is not fine enough to resolve the solid wall eg: solid object needs a least 2 cells a long the thickness for good meshing. So, you may need to use fix point to ensure you have at least 2 cells along the thickness of thin wall object. Hope this help.
Attapon, did you figure it out? Was it poor mesh resolution?
