Dear all,

I'm having trouble executing a cfd-model. The geometry is a simple micro-channel (1mm by 10 by 150mm) made of copper which has a certain temperature. This is cooled by water of which I know the input velocity and initial temperature at the inlet. I want to model the temperature of the fluid and the solid over the length of the microchannel. However, i have to state the temperature of the fluid at the solver. Consequently, after applying the boundary and initial conditions, the result is that the fluid is immediately the ambient temperature. Is there anyway I can model the temperatures by only having the input of fluid velocity, initial fluid temperature and wall temperature?

Edit: Forgot to mention, im using simcenter thermal/flow

With kind regards,
