njssdfu is on a distinguished road
I'm trying to do smoke simulation in CFX. I defined smoke with ADDITIONAL VARIABLE.
1. How could I shown in results mass ratio of fresh air and smoke?
2. How could I define new contour. I would like to have contour of visibility. I know the equation but I don't know where to define it.
m-is defined in additional variable.
Thank you for help. Or please send me page number in user guide because I can't find it.

EDIT: Ok I solved problem with second point. It is showing some strange result but I will corect it. So help me just with the first one. I can't find that type of contour.

1) If you equation a certain additional variable quantity to a certain mass fraction then this is straight forward.
2) Define this as a variable in CFD-Post. Then you can plot an isosurface of it.
