| Abstract: | The basic principle of moving least square method and approximate function structure method were introduced.Using point collocation method and the principle of moving least square method,one moving least square & point collocation meshless method based on moving least square thought was proposed.The implementation of this method does not need background mesh,does not need to carry on Gauss integral.The characteristic of this method is small in calculating amount and simple in boundary condition processing,which is a true meshless method. |
