Asynchronous time integration while achieving zero interface energy
Autor: Dvořák, Radim; Kolman, Radek; Falta, Jan; Neühauserová, Michaela
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)This contribution deals with an asynchronous direct time integration of the finite-element model. The proposed method is applied to the phenomenon of wave propagation through an elastic linear continuum. The numerical model ... -
