Ramp inlet temperature
 
Hi all,

I am modelling a nozzle and I cannot get a stable simulation so I am trying to ramp my inlet temperature, but have not been successful. I have previously ramped my inlet flow rate using fileName and creating a ramping-file, I am trying to do the same thing for my temperature.

Does anyone know if I can do this using the totalTemperature BC? If not, then can anyone suggest a BC that will let me ramp the temperature?

Thank you for any help that anyone can offer.
Tom
