Regularized meshless method irregular domain desingularization technique weighted diagonal element approach numerical integration
2010/10/22
The regularized meshless method (RMM) is a novel boundary-type
meshless method but by now has mainly been tested successfully to the regular domain
problems in reports. This note makes a further inv...
