抄録

We present a fractional step, finite element scheme for free boundary problems of viscous fluids. In the first half-step the Stokes problem is solved using the mini finite element, which is one of the simplest elements satisfying the inf-sup condition. In the second half-step the convection problems are solved using a newly developed upwind scheme. The position of the free boundary is determined by tracing the nodal points lying on the free boundary at a previous time. We apply this scheme to a model equation derived from a compression molding problem and show its efficacy.
