This application note illustrates the transient development of microwave field in an air-filled waveguide with an L-bend geometric feature.   The Time-Domain Electromagnetic Wave Solver Module of the VizEM Electromagnetics Modeling Software Package developed by Esgee Technologies Inc. is used for this problem. The 2D planar waveguide geometry and the computational mesh used for the simulations of this problem are shown in Figure 1.  The waveguide is 100 cm long in the horizontal direction (x-direction) and

We are pleased to announce the release of OverViz Simulation Suite version 2.2. This includes the first release of VizGrain with full integration into the OverViz simulation framework, enabling macro-particle dynamics for hybrid plasma-fluid-electromagnetics simulations. Key new features include: Direct Simulation Monte Carlo (DSMC) particle modeling in VizGrain; dust particle and boundary surface changing; enhanced particle collision modeling; new robust, compressible flow solver in VizFlow applicable across wide range of Mach numbers; now support multiple

The VizSpark software is used to perform a 2-D simulation of a model spark plug channel with cross-flow. Coupling between arc physics and conjugate heat transfer to the electrode was performed. The ability to predict spark restrike events was also demonstrated. Furthermore, an estimate of electrode ablation is also made. The spark plug has been a reliable source of ignition for well over 100 years.  The ignition source plays a pivotal role in the efficiency

This application overview discusses the modeling of a flow-through Inductively Coupled Plasma (ICP) reactor with VizGlow and provides an example of tightly coupled multi-physics simulations with the software.  Discharge physics including multi-temperature, multi-species transport, and finite-rate plasma chemistry effects are coupled to electromagnetic wave phenomena driven by inductive coils, and a bulk fluid flow through an inlet/outlet configuration.

The geometry and mesh for the plasma discharge simulation are shown in Figure 1.  The axisymmetric discharge

3D Microwave Plasma MWP Simulation in VizGlow

This example application simulates a steady microwave field in a three-dimensional plasma reactor using in semiconductor materials processing.  The Frequency-Domain Electromagnetic Wave Solver Module of the VizEM is used for this problem. The geometry for the simulation is shown in Figure 1 and comprises a cylindrical processing reactor with an air-filled waveguide port in the top center of the reactor.  The waveguide is rectangular in cross section and comprises an L-bend with a 45o mirror surface
