Cannot find macros for some terms (UDF)
I am trying to add a source term to the turbulent kinetic energy dissipation equation. Unfortunately there are some terms I don't know how to add.
For instance, is there any macro to get the velocity derivative in time? I know it is easy to create myself but I want it to depend on the time discretization scheme (I know, it is not that difficult).
Second of all, is there a direct macro for the turbulent production? It seems quite annoying having to play with the S tensors...
Thank you for your help!
Re: Cannot find macros for some terms (UDF)
I found a bigger problem: I cannot access the value of turbulent kinetic energy at the previous time step! Any ideas?
