guy_smiling is on a distinguished road

I posted this problem a week ago or so, but I haven't received a response so I thought I'd repost:

I'm running rhoCentralFoam and I want to solve for supersonic, compressible flow for two mixed, unreacting gases. My thermophysicalProperties file looks like this:

thermoType ePsiThermo<pureMixture<sutherlandTransport<specieT hermo<hConstThermo<perfectGas>>>>>;

mixture air 0.5 28.96 1004.5 0 1.458e-06 110.4;
mixture he 0.5 4.003 5193.0 0 1.387e-06 48.46;

I think I'm using this wrong. I think I should be using basicComponentMultiMixture, but I haven't found any examples using that mixture properties type. Can I just replace 'pureMixture' with 'basicComponentMultiMixture' and use the first numbers (the 0.5) as the fraction of the gas? I try that and I get that it's not a valid type.

Any help is much appreciated. Thanks
