Hello


I am trying to use tabulated properties for supercritical CO2 but I am having a hard time. My thermophysicalProperties header is just like this:

thermoType
{
    type            heRhoThermo;
    mixture         pureMixture;
    transport       tabulated; 
    thermo          hTabulated; 
    equationOfState icoTabulated; 
    specie          specie;
    energy          sensibleEnthalpy;
}

The dictionaries for rho, cp, mu and kappa have 1200 rows each. I am using the solver rhoPimpleFoam.


This is the error that I am getting:

Does anyone have worked with these tabulated properties, or with supercritical CO2?

Hello Dekkers,
I think there might be problem with some of your tabulated properties. I think you have some subroutine that used these tabulated values and returns some calculation to a field variable. So the problem in your model in return statement there might be there is something that is getting divided by zero.
I am not sure .But I hope this helps

Hi,Dekkers. I have the same setting as you describe. I also encounter the same issue. I have spent many days on this, but not solved. Have you solved this problem?
