Hi everybody
I’m trying to use butterfly to simulate thermal environment in city area. The snappyHexmesh is a fine tool to refine the grids adjacent to the walls. I met a problem that the refine region can not be recognized when the case made of “caseFromGeos”, but works fine with cases made of “caseFromWindtunnel”. Is that the bug of the plug-in or I misunderstood something? Any one can help?
I got the same error, and solved the problem as follows.
Double-click on Butterfly_Create Case from Geometries and modify line 57 as follows.
// case.add_refinement_region(reg)
case.add_refinementRegion(reg)
It was just a typo.
Thank you kinonotofu. I found that before which maybe a small misquote of the codes. But I gave up the next step of using Openfoam as the CFD solver since it’s really hard to come out with the suitable mesh and get convergence, especially for non-isothermal questions.
