Default Running rhoCentralFoam without specification of Temperature

I wanted to ask if the specification of temperature is necessary for simulation of pressurization with rhoCentralFoam or if there is a way not to specify it.

Thanks in advance!

I'm not sure if I completely understood your problem, but:

rhoCentralFoam simulates compressible flow. It solves the energy equation. The internal energy depends on temperature.
Finally you derive pressure from temperature via the equation of state (perfect gas: p=rho*R*T).

So, running a compressible flow simulation without having a specified temperature is impossible.

Hope that helps.
