Class 3 Error
If a user surface is imported into CFX Post for a particle transport model calculation, and the surface is then used for evaluating expressions involving particle mass flow rates, then the computed answers are incorrect.
This is caused by the software not knowing any integration point information for the user surface and then injudiciously trying to calculate mass flows from the density and velocity, but using the fluid rather than parti
Restrict mass flow calculations to boundaries, or locators created in CFX Post.
