A Fixed-Grid Front-Tracking Algorithm for Solidification Problems. Part I - Method and Validation
This paper presents a method for solving moving boundary problems associated with phase-change. This method is an explicit interface-tracking scheme that involves the reconstruction and advection of the moving interface on a fixed grid. Three distinct steps are undertaken to handle the movement of the interface: advection and reconstruction (tracking); calculation of normal velocities; and the ...
متن کاملA Fixed-Grid Front-Tracking Algorithm for Solidification Problems. Part II - Directional Solidification with Melt Convection
A numerical study of directional solidification has been performed using a fixed-grid front-tracking algorithm. The directional solidification of pure tin, as well as the horizontal Bridgman growth of pure succinonitrile, were investigated. In both cases, the growth front was stable and non-dendritic, but was significantly distorted by the influence of convection in the melt and, for the Bridgm...

متن کاملModified Fixed Grid Finite Element Method in the Analysis of 2D Linear Elastic Problems
In this paper, a modification on the fixed grid finite element method is presented and used in the solution of 2D linear elastic problems. This method uses non-boundary-fitted meshes for the numerical solution of partial differential equations. Special techniques are required to apply boundary conditions on the intersection of domain boundaries and non-boundary-fitted elements. Hence, a new met...
