From function emptyFvPatchField<Type>::updateCoeffs() in file fields/fvPatchFields/constraint/empty/emptyFvPatchField.C at line 150. so can somebody tell me what problem it is and how i can fix it thank you very much |

Look at your Mesh in Paraview, maybe you see an obvious mistake. i guess some points are mixed up.
PS: your post looks like you were in a hurry, is that true? |
