Hi,

I tried to get previous time step values in a UDF, but every time I call a second previous time step macros, no matter which one, e.g., C_R_M2(c,t), C_U_M2(c,t), or C_T_M2(c,t), I get Segmentation fault error.

The fl process could not be started.


It doesn't happen for the first ones (previous time step, _M1 macros). The _M1 macros work good.

Should I do something in Fluent before using the second previous time step macros (_M2)?
Does Fluent store these second previous time step values by default?
Any suggestion?
