Sounds fun. Any links to the various ideas about melting Moon/Mars rock to 3d print buildings? 

If you need to use air later on then you may need to be a bit careful with the multiphase models. For now, single phase with solidification/melting should be OK. So, I think my comment re splitting the code sections and being more careful with the IF statements will stand. 

I don't know if == means a more accurate check than = but remember computers will have some numerical rounding, 0.99999999999999 and 1.000000000001 could easily creep into REAL definitions of 1.0
