C_UDSI_M1 and C_YI_M1 UDF Run time error

mkh_sakr · June 20, 2018, 15:04

Hello,

I have a run time error when I include the macros C_UDSI_M1 and C_YI_M1 in UDF to access variable values at previous time step.

I allow for some time step of the running before I use these macro but once it is the time to call them, the simulation crashes.

Any help would be appreciated.

Thanks.

Do the corresponding current time step macros work, i.e. C_UDSI and C_YI? You could also check if this data from previous time steps are freed from memory by default (try via TUI: /solve/set/expert). Lastly, if the macros are still not working, you could save this data in user-defined memory and update the variables each time step yourself (automatically).
