CFD Online Discussion Forums - problem with comfort function (PPD PMV) in post-processing

Hi,

I want to use the function "comfort "(https://cpp.openfoam.org/dev/comfort_8C.html) in post process to calculate the PPD and PMV field, I have calculated the T and U fields (with buoyantSimpleFoam).

the "comfort" file I put in system is:

Code:

    comfort

    {

        libs            ("libfieldFunctionObjects.so");

        type            comfort;



        clothing        1.0;

        metabolicRate   1.2;

        extWork         0;

        relHumidity     50;

        Trad   292; //I have tried with 292, 19 (if they are C) and without this line

    }

after using the comand line: postProcess -func comfort -time 1000
but I received this error

Do you know what is the problem?
What LHS and RHS are?
