massive_turbulence is on a distinguished road
Right now I have the following thermophysicalProperties file

Code:
/*--------------------------------*- C++ -*----------------------------------*\

| \\      /  F ield         | OpenFOAM: The Open Source CFD Toolbox           |
|  \\    /   O peration     | Version:  v1806                                 |
|   \\  /    A nd           | Web:      www.OpenFOAM.com                      |
|    \\/     M anipulation  |                                                 |
\*---------------------------------------------------------------------------*/
FoamFile
{
    version     2.0;
    format      ascii;
    class       dictionary;
    location    "constant";
    object      thermophysicalProperties;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

thermoType
{
    type            heRhoThermo;
    mixture         pureMixture;
    transport       sutherland;
    thermo          janaf;
    equationOfState perfectGas;
    specie          specie;
    energy          sensibleEnthalpy;
}

CHEMKINFile         "<case>/chemkin/chem.inp";
CHEMKINThermoFile   "<case>/chemkin/therm.dat";
CHEMKINTransportFile "<case>/chemkin/transportProperties";

newFormat       yes;
inertSpecie Cs;

Cs
{ 
    specie 
    { 
        nMoles       1; 
        molWeight    132.90543; 
    }    
}
What I wanted to know is if I needed to declare "inertSpecie Cs;" if I declare it again below that line for Cs. I have my other declaration in a chemkin file but none of them have the molWeight for Cs? I'm not really certain if maybe it should be more like this instead
