Default steady state for a standing ultrasonic wave

flueth is on a distinguished road
I intend to simulate an ultrasonic standing wave by using an pressure inlet with a reflector. The pressure inlet is supposed to oscillate sinusoidal to generate the wave. Now the question: Is it possible to generate the steady state by using a .ttab profile while the time step size is much larger than the profile step sizes?
Do I need to calculate in the same time step size as the profile step size is?
What could be the alternative to simualte this if Iīm only interested in the steady state and therefore donīt want to calculate in the transient mode?

Thanks a lot!
