execute udf in ss & transient simulation
 
hello
i use "DEFINE ON DEMAND" in my udf.i hook it by "User-Defined Function Hooks"
in "Execute at End".
in steady state simulation, udf executed at end of every iteration.
but in transient simulation it executed at end of each time step.
i use "DEFINE ADJUST" in stead of "DEFINE ON DEMAND" in my udf and hook it in
"User-Defined Function Hooks" in "Adjust" and it execute at every iteration in transient and steady state but it hasnt any effect on my simulation.
what can i do to execute udf in every iteration in transient simulation?
