Setting internal flow Boundary Conditions on OpenFOAM

Matheus.Costa · November 24, 2020, 09:40

Hi there OpenFOAM community, I would appreciate a lot if any of you could help me out, I'm using snappyHexMesh to generate a tube in order to run an internal, incompressible, turbulent flow. I'm using as a base for the code the motorcycle tutorial, but it's originally external flow, I've tried tinkering the boundary conditions for the variables inside the 0 folder but setting the tube as a fixedwall still made the the flow run over it instead of inside. Do i need to import only the "shell" of the tube without both surfaces that covers it? Thanks in advance!

Hi Matheus,

Are you sure that you are setting 'locationInMesh' keyword in 'castellatedMeshControls' correctly to choose the inside of the tube as your flow domain?

Cheers
