Hi, i hope some could solve my problem.

I need a dynamic velocity from the inlet of a pipe but i cant find a button for that. I just can type in a constant for the velocity magnitude. Is it possible to ramp up the velocity from 0 to 1 sec constantly. For example:

0 sec----->0 m/s
1sec------>1 m/s

Would be so nice if someone could help me.

You can do this with a transient simulation
