Abstract

In this research, CUT CELLs LEVEL SET METHOD despite of classic LEVEL SET METHOD is presented to evaluate more accurate grain burn-back analysis. This method is included of a Cartesian grid and by determination of the minimum distance to the grain boundary, boundary cells are specified. In order to investigate grain boundary condition with respect to Cartesian grids, two algorithms of perfect CUT CELLs and selected CUT CELLs are considered. In the perfect algorithm, all possible states (thirty states) for cutting cells by boundary lines, are considered. However, in the selected algorithm, more application states are considered. Comparison of results between classic, perfect and selected CUT CELLs LEVEL SET METHOD prove, that CPU time increase, from classic to CUT CELLs methods. However, accuracy of results increases also. The results of the selected method have a similar accuracy with a significant reduction in CPU time with respect to perfect method.
