Hello everyone,

I’m simulating phase change and want check if my model is accurate, thus I’m simulating a 1-D stefan problem. I’d like to know where the location of the phase change front is i.e. where the liquid fraction 0.5 and plot this location over time. How can I do this?

Kind regards,  
Jeroen
