reading velocity profile at each time step
 
hello everybody,

i am simulating a 2D flow in an axisymmetric tube.

there are two meshed tubes, one straight and another converging-diverging.

(that is because we cannot know the outflow conditions of the straight tube and also some flow data from it are needed for presentation)


during steady-state simulations, i was writing the outflow velocity profile of the first and then feeded it as inflow profile to the second.

(File --> Write --> Profile... & File --> Read --> Profile).



any ideas how to do it, for each time step, during transient simulation ???


using a UDF or by Executing Commands after each time step?

and what possible structure would this have?


thank you in advance...
