| Research Abstract |
In this research, we aimed at extending the discrete variational derivative method to finite element framework, and got the following results.
First, we showed that in the spatially one-dimensional case a finite-element version of the discrete variational derivative method can be formulated only with H^1 elements, and in fact applied the new framework to several typical partial differential equations. Then we extended the framework to spatially two-/three-dimensional cases, where we applied the method to the Ginzburg-Landau equation and confirmed the scheme in fact successfully works. Finally, we introduced a new technique to linearize the resulting schemes, and checked by numerical experiments that computational complexity can be decreased.
