The mesh is not enclosed

Altair Forum User

Hello,

When trying to mesh a surface in CFD Tetramesh, the error 'the mesh is not enclosed' appears. However, I've checked the geometry and there are no opened surfaces. Also, in Automesh, no errors show up and I can mesh normally. I don´t know why this happens and would really appreciate it if somebody helped me.

Hi Pablo I

 

I hope you have done 2D tria mesh using Automesh. For doing an volume tetra mesh, the mesh should be an enclosed volume ie; No free edges.

 

Try fixing the free edges and check for equivalence. Go to Tools > edges and check for free edges and equivalence nodes if any

If that doesn't work, share your model please
