jpapg is on a distinguished road
I know that there are other people having the same problem, as I've seen from a few other threads. No one seem to have an answer on this yet.

So I confirm that previous time step macros (like C_P_M1, C_U_M1, C_P_M2, etc) are NOT available for use in my UDF. Any access to these results in a ACCESS_VIOLATION message.

There's a note in the manual saying that "C_T_M1 is available only if user-defined scalars are defined". If that is true for ALL previous time step macros, then we can use them only in conjunction with user defined scalars.

Please confirm !
