Three Dimensional Monte Carlo Device Simulation with Parallel Multigrid Solver

We present the results in embedding a multigrid solver for Poisson's equation into the parallel 3D Monte Carlo device simulator, PMC-3D. First we have implemented the sequential multigrid solver, and embedded it into the Monte Carlo code which previously was using the sequential successive overrelaxation (SOR) solver. Depending on the convergence threshold, we have obtained signi cant speedups ...

Developing a Device for Automated Peritoneal Dialysis

Background: Peritoneal dialysis (PD) is an efficient alternative for hemodialysis. Removal of waste metabolites and excess water from the blood circulation are the two main tasks done during dialysis. These are done by using a filter; in PD, the naturally semi-permeable peritoneal membrane acts as the filter. Automated PD machines control intelligently the operations to enhance the efficiency a...

Practical Use of a Hierarchical Linear Solver Concept for 3D MOS Device Simulation

Three-dimensional device simulations of sidewall trench-isolated MOSFETs involve Linear systems of equations that are extremely ill-conditioned if the geometric channel length exceeds 2pm. Since conventional preconditioned iterative methods tend to fail in such cases we have implemented a robust iterative linear solver using a hierarchy of incomplete factorizations of the coefficient matrix.

Verification of a CFD solver in near ground effect for aerodynamic behavior of airfoil NACA 0015

Numerical investigation was performed on NACA 0015 which is a symmetric airfoil. Pressure distribution and then lift and drag forces are verified. Changing of ground clearance was a considerable point. Also the angle of attack was changed from 0° to 10°. Pressure coefficient reaches its higher amounts on the wing lower surface when the ground clearance diminishes. Increment of the angle of atta...

A Flexible Meta-solver Framework for Constraint Solver Collaboration

The solving of multi-domain constraint problems with the help of collaborating solvers has seen extended interest in recent years. We describe the implementation (Meta-S) and extension of a previously proposed theoretical framework of cooperating constraint solvers. Meta-S allows the dynamic integration of arbitrary external (stand-alone) solvers to enable the collaborative processing of constr...
