Modify specific heat ratio/polytropic index in OpenFOAM
 

Hi Foamers,

I am using, Openfoam 2.0.x, dieselEngineFoam to simulate diesel engine with a reduced mechanism.

I found out that the default gamma value (specific heat ratio) in Openfoam is 1.37. The gamma value that I want for my simulation is 1.36.

Any hints on how to modify this gamma value to the value I desire?

Thanks in advance for any hints.
