Unwanted Mesh Towards Geometries in Internal Flow

MateusLatt · May 6, 2018, 01:30

Hello,

I am trying to create a mesh for a geometry that I drew in solid works and converted it to .stl. I am using snappyHexMesh for the task, but when it finishes the meshing procedure, the background mesh keeps around my geometry. I am simulating an internal flow into a combustion chamber, so this mesh around (In my case it's named internalmesh) the geometry is messing up the simulations. I would thank a lot if anyone could help me, i was trying to use Salome too, but I thing the problem may be a wrong setting in snappyDict.

Most likely your STL has holes.
