Abstract:
A new m ov ing m esh m e thod is g iven in this dissertation. Key idea of our m ethod is that the m esh shou ld adapt the so lutions cha racter and have som e sm oothness. The d istribution o f the nodes is go tten by a var ia tiona l problem, w hose Eu ler-Lagrange equation is the new mov ing m esh equation. Why and how to form the new m ethod is in troduced in de tails. Num er ica l results in two-po int boundary prob lem s and boundary layer problem s are v ery encourag ing and c lear ly to show that in m any cases them ethod can con tro l them esh m o tion
