      In transient mode, which parameters do I need to include in my code for the DEFINE_PR_RATE macro? How can I ensure that all variables are updated in each interaction and at each time step? The code works fine in steady-state, but when I convert it to transient mode, it gives me a fatal error. Do I need to include time variables in the code? If yes, how should I do that? The UDF manual doesn't explain how DEFINE_PR_RATE changes for transient cases?

      It should behave in the same way. Transient just means we solve for a time step, so rates etc are still valid.
