Good day Foamers,
Thank you for reading my post. I have a very simple and repeatedly asked question. Sorry I did not find any satisfactory solution yet. I have axisymmetric 2D mesh of a simple bubble enclosed in rectangular domain. I just consider 1/4 portion for reduction. I make the mesh in fluent in 2d plane and save it in ascii format .msh. Afterwards i used https://github.com/krebeljk/wedgePlease utility to make it axisymmetric grid for wedge boundary. Every thing goes successful. The problem started afterward. When i solve the generated grid for my case (Which is correct), I get the following Error. Wedge patch 'wedge1' is not planar. At local face at (10.6613 -277.657 0.465485) the normal (-0.0436194 -1.58485e-17 0.999048) differs from the average normal (-0.0436195 -4.45833e-08 0.999048) by 2.40193e-14 Either correct the patch or split it into planar parts I tried to dig out the problem and after doing certain recommendations like: writeFormat binary; //<-KEEP binary writePrecision 12; //<- Make it up to 12 or more if you want I came to the conclusions that actually it is because of the common boundary that is generated by default frontAndBackPlane which remains empty in most cases. However in my case it is Wedge boundary condition. Now the problem is how to split this fron and back plane to two wedge boundary in polymesh file in constant folder. If anybody senior can recommend me a very simple method to get rid of this problem, I would be extremely indebted to you. Other way around i know that i can solve this simple case in ANSYS by modelling 3D mesh with 5 degree of wedge and import 3D mesh and name the two wedges separately. But it will not work for my future understanding of the problems. Thank you so much for reading my post. Regards, Danny |
