Hey,
I have a problem when using cfMesh (and snappyHexmesh). I want to mesh a 3D domain where my object of interest is a cone (which I think is the problem). The mesh ''imprints'' characteristic pattern on the geometry that then appears on my pressure distribution on the surface and causes the solver to diverge. I attach a picture of the pattern I am talking about to this post. Has anyone encountered this issue before? If so, have you figured out a way of dealing with it? I tried splitting the cone surface in hope it would break the symmetry of the patter but unfortunately it did not work. --> meshDict <-- maxCellSize 0.008; // (MANDATORY) Maximum cell size in the mesh [m] surfaceFile "constant/triSurface/OK_m.fms"; localRefinement { "coneBottomBack" { additiodditionalRefinementLevels 2; refinementThickness 0.006; //[m] } "coneBottomFront" { cellSize 0.0004; } "coneTopBack" { additiodditionalRefinementLevels 2; refinementThickness 0.006; //[m] } "coneTopFront" { cellSize 0.0004; } } objectRefinements { cone1 { type cone; cellSize 0.001; p0 (1e-4 0 0); p1 (0.404 0 0); radius0 0.01; radius1 0.08; } } |
