- W2385871795 abstract "The assumption in traditional numerical simulation method for time and space are independent of each other. This assumption has clearly physical meaning and is widely applied in practice. However,since this treatment can not reflect the inherent relation between time and space variables,the time discrete precision will be lost.Based on Hamilton variational principle,the weak form equivalent to one-dimensional finite domain wave equation is founded. Using the first order time and space interpolation foundation,two numerical models relying on Gauss and Node integral criterion respectively are presented for wave problems. The accuracy and calculation characteristics are compared between the two numerical discretization methods. The calculation results show that the node integral unit model is better in performance than the Gauss integral element model." @default.
