    Can anyone recommend a good software for modeling the liquid metal profile and solidification segregation of various materials during vacuum arc (VAR) melting?  Many thanks in advance...

    Hi Joe
    Leoben University has developped a software 
    look at article : j o u r n a l  of ma t e r i a l s  r e s e a r c h  and  technology  2 0 2 2 ; 1 9 : 1 8 3 -1 9 3
    Numerical modeling and experimental validation

    Dear Joseph,
    We use MagmaSoft for casting and solidification simulations at Missouri S&T. As any other sim software, it has some limitations, but you can use it for approx. predictions.
    Regards.

    Thank you Mario – just to confirm, you use that for VAR furnace modeling?

    I have experience using MeltFlow-VAR. This product is by Innovative Research LLC. http://inresllc.com They also make a package for ESR that is very similar. This has been around for many years and there are a fair number of published articles discussing the results.

    Joseph, are you looking for macro or micro-segregation?  For the latter, CALPHAD based tools such as Thermo-Calc can give you more information on the chemical inhomogeneity during solidification.

    Dear Josef,

    Microstructure prediction during solidification can be well solved by PhasePot software (is comercial: https://phasepot.com/software). 

    With very best wishes,
