WitrynaIn this article, we present an accurate three-grid-point compact finite difference scheme for solving this system. To this end, we first follow the penalty method and transform the free boundary system to an approximate PDE system in a fixed domain, and then introduce an intermediate function for the first-order spatial derivative in the PDE.
