when analyzing nonlinear devices, which can lead to an 80% reduction of the computational time with respect to the standard CN᎐FDBPM technique.

From the presented results, it can be stated that the proposed technique can be a very fast and inexpensive simulation tool for the analysis and design of slightly powerradiating 3-D nonlinear optical devices with small requirements on the reflection coefficient from the numerical boundaries.

The article treats the question of how to numerically solve the Dirichlet problem for the Stokes system in the exterior of a three-dimensional bounded Lipschitz domain. In a first step, the solution of this problem is approximated by functions solving the Stokes system in a truncated domain and sati

We present a numerical algorithm for the determination of muscle response by the ÿnite element method. Hill's three-element model is used as a basis for our analysis. The model consists of one linear elastic element, coupled in parallel with one non-linear elastic element, and one non-linear contrac
