jherb is on a distinguished road

I am looking for a tutorial/example with buoyantPimpleFoam and thermoType hRhoThermo<pureMixture<icoPoly8ThermoPhysics>> and a temperature dependent density, i.e.
        rhoCoeffs<8>   ( 1000 XXX 0 0 0 0 0 0);
with coefficient(s) of the polynomial of the density which are not 0.

I tried the hotroom tutorial for buoyantPimpleFoam with the properties of water, but it crashes immediately. If I set the density to a constant values, the example works. (I also tried some "open" geometries with an inlet and outlet, e.g. pitzDaily, but this didn't help either.)

Any ideas?

Thank you very much
Joachim Herb
