(New to OpenFoam) I am working on simulating a concentric-tube heat exchanger. Now since this requires multi-region meshing, I have planned to mesh the complete region first then divide it into 3 regions using topoSet. But I want to refine the surface of the pipe (which is in between the outer fluid and inner fluid).
Now to refine the surface of the pipe if I use the stl surface file of the pipe then I am not able to do the complete meshing (because if the point locationInMesh lies in the inner fluid then only the inner part gets meshed and if it lies in the outer fluid then only the outer gets meshed) So my question is how do I refine the surface of the pipe and do the complete meshing at the same time? Please suggest tutorials as well for whatever solution you suggest as this is my first project on OpenFoam Thank you in advance. This is how my geometry looks like (side-view) (let me know if you need any more information) (P: InnerFluid, Q: Pipe, R: OuterFluid) |
