Ohh that is really sad to hear.

So what model is this udf written for if i have to do it myself? say I am a simple cylinder with free stream flow on it and if i compute area average of pressure on the cylinder wall with this udf and if i print put from the reports it should be the same?

I am trying to understand what is this udf written for.

Please let me know what exactly is the purpose of the udf (Example: Global Summation of Pressure on a Face Zone and its Area Average Computation) what kind of model will this work on, will this work on the model as mentioned above?
