UDF is not working for axisymmetric model? Same UDF is working fine for planar model. Is there any limitation with Axisymmetric models.

1. For axisymmetric models in ANSYS FLUENT are made on a 1 radian basis. When you are using certain data access macros ( for example, F_AREA or F_FLUX) for axisymmetric flows, your UDF wants to multiply the values by 2*PI( using macro M_PI) to get the desired values. 2. For axisymmetric cases, axis boundary should be aligned with Y = 0 line. 3. Please check the above conditions, UDF will work fine.
