stationary flow - transient temperature

Nicola

Hey all,

I have a complex geometry with two separated fluids with constant velocities and

1.) the same temperature which differs from the solid temperature. I want to calculate the heating up of the solid

2.) one fliud with constant temperature and the other with a varying temperature ramp. I also want to calculate the heating up of the solid

As I get a maximum time step of 0.02 s for my flow condition it is quite uncomfortable to calculate fully transient. Is there a possibility to treat the flow as stationary and only the conjugate heat transfer as transient? How can I do the set-up for this calculation?

Regards,

Nicola
