3D Grid Generation for Semiconductor Devices Using a Fully Flexible Refinement Approach
نویسنده
چکیده
We present a new algorithm for the generation of 3-dimensional (3-D) grids for the simulation of semiconductor devices. The fitting of the device geometry and the required mesh density is obtained by partitioning the elements at an optimal point at each refinement step. This allows the fitting of more general 3-D device geometries and the reduction of grid points in comparison with previous grid generators.

متن کاملNovel Algorithms for Modeling Sedimentation and Compaction using 3D Unstructured Meshes
In this paper, we discuss some novel techniques for modeling sedimentation and compaction using fully unstructured meshes. The numerical modeling of the sedimentation process is a critical part of basin simulation and synthetic stratigraphy modeling. Normally, structured curvilinear meshes are used to represent sedimentary sequences to be deposited during the simulation. Using this approach, 2D...
متن کاملDC Voltage Control and Power-Sharing of Multi-Terminal DC Grids Based on Optimal DC Power Flow and Flexible Voltage Droop Strategy
This paper develops an effective control framework for DC voltage control and power-sharing of multi-terminal DC (MTDC) grids based on an optimal power flow (OPF) procedure and the voltage-droop control. In the proposed approach, an OPF algorithm is executed at the secondary level to find optimal reference of DC voltages and active powers of all voltage-regulating converters. Then, the voltage ...
متن کاملBehavioral Modeling and Simulation of Semiconductor Devices and Circuits Using VHDL-AMS
During the past few years, a lot of work has been done on behavioral models and simulation tools. But a need for modeling strategy still remains. The VHDL-AMS language supports the description of analog electronic circuits using Ordinary Differential Algebraic Equations (ODAEs), in addition to its support for describing discrete-event systems. For VHDL-AMS to be useful to the analog design ...
