....mesh function X vary in the literature. One direct method is to mimic the formula for T and to introduce a further function H such that X = H(X;U) 4. 8) This is a natural strategy for certain hyperbolic equations as it can correspond to advecting the mesh along the ow of the solution, see [37] where it is combined with a powerful multisymplectic approach to study various problems in uid mechanics. A similar strategy is 11 also adopted by Dorodnitsyn and his co workers for a general class of groups [16] To give a scale invariant scheme we require that H(X;U) satisfy H( 1 X; ....

....multi symplectic PDEs like, for example, M t z K x z L y z = r z S(z) This also implies that the schemes can be applied to the corresponding stationary problems characterised by t z = 0. Further results on multi symplectic methods in the context of finite volume methods can be found in [17]. Acknowledgement. We like to thank Tom Bridges for the introduction to his framework of multisymplectic PDEs and for many stimulating discussions during the preparation of this paper. ....
