In the solidification and melting model, the liquid fraction (beta) is defined as given in this link: LINK REMOVED - Rob

I was wondering if there is a way to replace this definition with a custom definition where beta is defined using the curing rate function instead (perhaps using a UDF), so that beta is no longer a function of temperature as in the original definition but instead a function of time. Is it possible to completely replace the default definition of beta in the solidification model with the curing rate function using UDF? If so, how would I be able to do this? Please advise.

Thank you.
