Extremely high Temperature needed to simulate pressurization with rhoCentralFoam
 
Hello Foamers,

I am trying to simulate pressurization inside a tube with rhoCentralFoam. With setFields I set a small area inside the tube that has high pressure (2 GPa). The static pressure is 100000 Pa. When I start to simulate, pressurization takes place but simulation crashes after less than 0.001 s. The temperature I chose for the high pressure field is 4500 K.

If I set the Temperatue inside the high pressure field to 20000 K the simulation does not crash but I am very assure that this value is too high.

Is this a setup issue? Do you know a way to calculate the needed temperature to set inside the high-pressure field?

Thanks in advance!
