Hi everyone,

I am currently running some simulations of a multiphase problem including a solid metal phase and an argon phase.
I've turned on the solidification and melting module and have an energy soruce term that turns on and off to allow solidification and melting of my materials.

Previously, while simulating an aluminium alloy with cell size of 3 μm^3, everything was ok as the solidification range was quite wide.

I am now trying to do the same simulation with a stainless steel alloy which has a really narrow solidification range (between 1658 and 1723 K), and, although it is overall ok, as you can see on the attached graph (I plotted the liquid fraction against the temperature for where the metal volume fraction is equal to 1), I am unsure of the accuracy of the mushy zone (the metal between the solidus and liquidus temperature, corresponding to the two green lines on the attached figure), as the range is really narrow regarding the cell size (the cells are 6 μm^3 cuboids)

I'd love to have your opinion, if the cell size need to be decreased to capture the evolution of the liquid fraction in the mushy zone or if it is still ok

Thanks a lot in advance !
