We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

  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.
