Least-squares collocation meshless method
Nettet5. mar. 2014 · In this paper, the meshless method based on the moving least squares is used for solving the inverse problem of parabolic equation with the time-dependent … NettetABSTRACT. We present a new meshless animation framework for elastic and plastic materials that fracture. Central to our method is a highly dynamic surface and volume sampling method that supports arbitrary crack initiation, propagation, and termination, while avoiding many of the stability problems of traditional mesh-based techniques.
