      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.
