Three-Dimensional Transient Electromagnetic Numerical Simulation Using FDFD Based on Octree Grids

three dimensional simulation and testing of radiative electromagnetic wave characteristics on electronic circuits using fdtd method

voltages and currents are induced into electronic circuit boards as electromagnetic waves are radiated on them. the strength of induction depends on the wavefront and the circuit board characteristics. in this paper, by solving maxwell’s equations using fdtd method and then by extending it by three dimensional simulation using the gpml criteria for boundary conditions and tf/sf technique, effec...

Three-dimensional direct numerical simulation of flow problems with electromagnetic control on parallel systems

Three-Dimensional Transient Electro-Thermal Simulation

We present a program package based on finite elements for twoand three-dimensional analysis of interconnect structures. Thereby, triangular and tetrahedral grid elements with quadratic shape functions are used. Two preprocessors allow a layer-based input of the simulation geometry and the specification of the boundary conditions. The main program calculates amongst other things the distribution...

Three-dimensional Transient Device Simulation with Minimos

Our device simulator MINIMOS has been used for the numerical analysis -of three-dimensional non-planar silicon MOSFET and GaAs MESFET structures. Here we present an extension of the program for the simulation of transient effects. This version of MINIMOS has further been enhanced by a new, highly accurate current integration method. The computational complexity of three-dimensional transient si...

Three-dimensional microscale numerical simulation of smoldering

A three-dimensional numerical tool for the simulation of smoldering in fixed beds of solid fuels is presented in this paper. The description is based on the microscale equations, in a detailed discretized image of the porous medium. Simplifying assumptions are used, but the local coupling of the transport and reaction mechanisms is fully preserved. A set of 2D and 3D simulations demonstrates th...
