Euler method

[′oi·lər ‚meth·əd]
(mathematics)
A method of obtaining an approximate solution of an ordinary differential equation of the form dy / dx = f (x, y), where f is a specified function of x and y. Also known as Eulerian description.
(mechanics)
A method of studying fluid motion and the mechanics of deformable bodies in which one considers volume elements at fixed locations in space, across which material flows; the Euler method is in contrast to the Lagrangian method.

We also compare the ASR method with the Linearly Implicit Euler method, based on solving an appropriate linear system involving the Jacobian of the nonlinear operator by using GMRES with the Additive Schwarz preconditioner as in ASR and we show that the ASR method is asymptotically less expensive.
