Dear Openfoam users,
I am having a problem with snappyhexmesh. My mesh is almost as good as I want it to be, but I am experiencing a problem with the layer addition. I have attached a picture of the problem. I also have attached the snappyhexmeshdict file. Feel fry to comment on other things that are not good. I have been playing around with featureAngle and nRelaxIter, but that did not give the desired result. Thanks!! |

Hi,
Looking at your dict file I'd recommend, first of all: - increasing the no. featureSnapIterations up to 20, say, just to be sure the process is complete - increasing the featureAngle in your addLayer control up to 90 (this should ensure that as many cells are added as possible, within other constraints) If that fails, then try: - increasing maxFaceThicknessRatio and maxThicknessToMedialRatio - reducing the relax and smooth iterations in addLayers to their original values - reducing mesh quality settings, especially the minimum volume Best of luck, A |
