A deforming E'EM (DFEM) analysis of one-dimensional inverse Stefan problems is presented. Specifically, the problem of calculating the position and velocity of the moving interface from the temperature measurements of two or more sensors located inside the solid phase is addressed. Since the interfa

## Abstract An enriched finite element method for the multiโdimensional Stefan problems is presented. In this method the standard finite element basis is enriched with a discontinuity in the derivative of the temperature normal to the interface. The approximation can then represent the phase interf
A ยฎnite element model of dendritic solidiยฎcation of multicomponent alloys is presented that includes solutal convection and is an extension of a previously developed model for solidiยฎcation of binary alloys. The model is applied to simulation of the solidiยฎcation of ternary and quaternary Ni-based a
## Coordinate transformation techniques. Here the unknown is mapped onto a regular geometrical region. The A 2D axisymmetric formulation for the solution of a directional solidification problem using an inverse finite-element method resulting transformed equations are then solved on this (IFEM) is
