Dear FiPy developers, Actually I want to solve the CahnHilliard equation for a multi-component, multi-phase flow. So, I am facing with a moving boundary problem. I am going to convert the problem to a fixed boundary one with a coordinate transformation. In this way, there is no need for remeshing. coordinate transformation: V = h/h_curr(t) gradient operator in the new coordinate system: NewGradOperator = e1(1/h_curr)(d/dV) + ei(d/dxi) where the first component is the direction along the height of the film. And use this NewGradOperator in CahnHilliard equation instead of the normal grad operator. Is it possibile to do such coordinate transformation in FiPy? Any idea how to do that?
Thanks a lot in advance. Regards, Hossein Sadeghi _______________________________________________ fipy mailing list [email protected] http://www.ctcms.nist.gov/fipy [ NIST internal ONLY: https://email.nist.gov/mailman/listinfo/fipy ]
