Hi guys,

I am using rhoSimpleFoam and cannot use the linear EoS even if it is defined in the thermophysical properties. I want to investigate the density change by changing just the pressure, not the temperature. The linear EoS condition may give a reasonable solution for my case because the fluid is a liquid.. I got the problem there --> FOAM FATAL IO ERROR: (openfoam-2312)
Unknown fluidThermo type
