Some old notes, running binary alloy model:

parameters = { "temperature_rayleigh_number": 8., "concentration_rayleigh_number": -9., "prandtl_number": 7., "stefan_number": 0.2, "schmidt_number": 6., "pure_liquidus_temperature": 0., "liquidus_slope": -0.11, "phase_interface_smoothing": 1./16., "autosmooth_maxcount": 16}

m, Delta_t, smin 4, 1./4., 0.0870 4, 1./8., 0.1519 4, 1./16., 0.0758 4, 1./32., 0.0917 4, 1./64., 0.0640 4, 1./128., 0.0625 4, 1./256., 0.0661 4, 1./512., 0.0635 8, 1./64., 0.0804 16, 1./64., 0.0842 32, 1./64., 0.0867

I also have many results with different parameters from running Phaseflow.

The idea is that it would be nice to have data showing for which intersection of parameters we can reliably obtain solutions.

However this is done should be scripted such that it can be automatically done again when we change our stabilization and regularization.
