Calculation of face vaules with udf
I have got a problem with the calculation of face vaules from cell center values. For an interior face i could caculate the face value either from the c0 cell side or the c1 cell side, using the cell values and the gradient. For a species it looks like this
and from c1
dr is the vector from cell center to the face center. Both face values should be identical but unfortunatly they are not. I tried it on a sturcured meshe with full converged soultion. Is there any other way to get consistent values for the faces?
Thanks for any suggestions
