Hello everyone
I want to make a 3D simulation of airfoil, I made the gonometry with Isis-cfd. I changed in boundary the name of patch in cyclic and also in file 0, but it displays me an error. Do you have a tip to unblock this bug please. Thanks a lot This is the error: [100] --> FOAM FATAL ERROR: (openfoam-2106) [100] face 0 area does not match neighbour by 192.6987% -- possible face ordering problem. patchrocBoundary100to15throughZmax my area:5.721409e-07 neighbour area:1.063766e-08 matching tolera nce:9.255939e-11 Mesh face:252543 vertices:4((0.3441662 0.1384074 4) (0.3460498 0.138489 4) (0.3460351 0.1387911 4) (0 .3441423 0.1387097 4)) If you are certain your matching is correct you can increase the 'matchTolerance' setting in the patc h dictionary in the boundary file.
