By default OpenFOAM uses Newton's method to find the temperature from the energy and pressure. This means that many evaluations of the h(p,T) function are required. Normally this is not a problem...

type heTabularThermo; means that the temperature will be determined by a table T(h,p). This is only needed if you also provide h(T,p) as a table with thermo hTabular;.

The code I published is currently only suited for the psiThermo model. For rhoThermo you will have to do the adjustments yourself I'm afraid. I would check for all files which mention psiThermo, look...

Tabulated thermophysicalProperties library

I've finally gotten around to cleaning up my code for using tabulated material properties so I can release it.

Keep in mind that it's still work in progress, so please tell me if you find any...
