I do some User Code in starccm+, f() is a function I want to calculate. its variables(arguments)are all from last time step and include itself. say, f(time step n) = f(var1_n-1, var2_n-1, var3_n-1.f_n-1). n-1 mean these variables are form n-1 time step.

How can I get the some value from last time step and then use them in calculation of the current time step? I tried it, but at every time step, when the user code is executed, the variables in it will be re-initialized, no information from last time step is kept in the memory. anybody have idea? Thanks very much.
