Particle in Cell (PIC): Error Estimates for Adaptive Grids
Juergen Geiser
This paper has been withdrawn by the author due to rewritting and skipping crucial sign errors.
Simulation of a Heat Transfer in Porous Media
Juergen Geiser
We are motivated to model a heat transfer to a multiple layer regime and their optimization for heat energy resources. Such a problem can be modeled by a porous media with differen…
Multiple Iterative Splitting method for Higher order and Integro-differental equations
Juergen Geiser, Thomas Zacher
In this paper we present an extension of standard iterative splitting schemes to multiple splitting schemes for solving higher order differential equations. We are motivated by dyn…
Embedded Zassenhaus Expansion to Operator Splitting Schemes: Theory and Application in Fluid Dynamics
Juergen Geiser
In this paper, we contribute operator-splitting methods improved by the Zassenhaus product for the numerical solution of linear partial differential equations. We address iterative…
Multiscale methods for Levitron Problems: Theory and Applications
Juergen Geiser
In this paper, we describe a multiscale model based on magneto-static traps of neutral atoms or ion traps. The idea is to levitate a magnetic spinning top in the air repelled by a…
Multiscale Splitting method for Boltzmann-Poisson Equation: Application for Dynamic of Electrons
Juergen Geiser, Thomas Zacher
In this paper we present a model based on dynamics of the electrons in the plasma using a simplified Boltzmann equation coupled with a Poisson equation. The motivation arose to sim…
Splitting methods for Levitron Problems
Juergen Geiser, Karl Lueskow
In this paper we describe splitting methods for solving Levitron, which is motivated to simulate magnetostatic traps of neutral atoms or ion traps. The idea is to levitate a magnet…
