Hi, In fluent it has been made a variable change such as: 2D(X,Y,Z) -> 2D-axi(r,theta,z). The correspondance is: X -> z Y -> r Z -> theta. In case you compute a force flux, you need to know that the theta depth is one radian. So to get the whole force you have to multpply your force by 2*PI.
Normally you do not need to do any adaptation when you write your formula in your UDF cause this change of variable allow a go from 2D to 2D axy without any change. It does exist some reference in the documentation, i have seen them once but i cannot refind them. good luck ! |
