You can change the polarization, center frequency, bandwidth, number of frequencies, substrate thickness and its material properties, and unit cell type circle, ring, split ring, etc. Add-on products expand the simulation platform for electrical, mechanical, fluid flow, and chemical applications. A charge exchange cell consists of a region of gas at an elevated pressure within a vacuum chamber. As a consequence, highly energetic ions tend to follow nearly straight paths, whereas less energetic ions follow more random paths. This makes it much easier to release beams with phase space ellipses of a certain size, shape, and orientation. The resulting charge exchange collisions create fast, neutral hydrogen blue and slow-moving argon ions green.
As the initial kinetic energy of ions is increased, their interaction with solid material becomes dominated by ionization loss instead of stochastic nuclear interactions. . However, the performance of the mixer can vary greatly, depending on its geometry. The Charge Exchange Cell Simulator app simulates the interaction of a proton beam with a charge exchange cell containing neutral argon. When the incident wave is defined by an electric field, the user can specify the initial value for the magnetic vector potential for the incident wave. The program can is designed to chemistry jobs, astronomy, quantum, earth sciences as well as mac erics.
Materials properties, supply phrases and boundary situations can all be arbitrary capabilities of the dependent variables. The example app computes the transmission probability of particles in the mixer. You can do this by varying antenna properties such as the geometric dimension and substrate material. This lumped port type can be used for multiexcitation or multitermination of, for example, a coplanar waveguide port or a differential port. The Boundary Mode Analysis study step is used for solving the mode field for numeric ports in the electromagnetic interfaces. The issue could affect, for example, models where an object reattaches to the source boundary after a full revolution. The direction of the field in each subelement of the port is defined by the Uniform element subnodes, where the direction between uniform element terminals, ah, defines the electric potential polarity.
A particular strength is its ability to account for coupled or multiphysics phenomena. An added feature of this app is the option to view it on either a narrow or a wide screen. A new Editor Tools feature enables you to quickly create standard interface components in apps. » » Comsol Multiphysics 5. Name: Comsol Multiphysics Version: 5.
The software lets you create 1D, 2D, as well as 3D spaces by using the partial derivatives of finite element method. Software rendering also supports 16-bit color graphics. Furthermore, it also got support for chemicals when dealing with gas mixture viscosity correlation. Simulated and experimental data agree well. Any number of modules can be seamlessly combined to handle challenging multiphysics applications.
Furthermore, it also has various capabilities as well as it can work as a great element for elasticity, fluid dynamics, gas dynamics in addition to electromagnetic. It is likely that only a fraction of the beam ions will undergo charge exchange reactions. In both cases, after the collision, it is possible to continue tracking the ionized species, neutral species, or both. Various plotting capabilities and numerous other powerful tools are there to help you with modeling, analysis, and simulation. A suite of add-on products expands this multiphysics simulation platform for modeling specific application areas as well as interfacing with third-party software and their capabilities. System Requirements For Comsol Multiphysics 5.
This is a very efficient manufacturing method for producing bandpass filters, which can readily be implemented on a GaAs wafer. The simulation app computes the efficiency of the charge exchange cell, measured as the fraction of ions that are neutralized, and records statistics about the different types of collisions that occur. As the initial kinetic energy of ions is increased, their interaction with solid material becomes dominated by ionization loss instead of stochastic nuclear interactions. The model calculates the transmission probability and visualizes the nominal trajectory of the transmitted beam. The Nonresonant Charge Exchange feature is used when the ionized and neutral species are of different elements or substances. It features a new parts library to use parameterized part for easy use.
When a fluid is pumped through the channel, the alternating directions of the cross-sectional blades mix the fluid as it passes along the length of the channel. Hardware rendering requires at least 24-bit color graphics. If the Particle Counter feature is a Particle Beam feature in the Charged Particle Tracing interface, additional variables for the average position, velocity, and energy of the transmitted particles are available. The Resonant Charge Exchange node is used when energetic ions undergo charge exchange reactions with ambient neutral atoms of the same element or molecules of the same substance. The new settings enable the user to define the exact wave form for the magnetic vector potential being solved for. Any number of modules can be seamlessly combined to handle challenging multiphysics applications. Learn more about the latest version of the software in this archived webinar.
The application includes support for structural hygroscopic swelling with the help of new multiphysics coupling. A suite of add-on products expands this multiphysics simulation platform for modeling specific application areas as well as interfacing with third-party software and their capabilities. You now have the option to include dynamic graphic updates to plots while solving. In a charge exchange cell, an energetic proton beam red propagates through a gas cell light gray that is maintained at a higher pressure than its surroundings. You even have the choice of selecting totally different physics and defining the interdependencies your self. This is a prime candidate for the 5G mobile network system.
The Laminar Static Particle Mixer Designer app computes the fluid velocity and pressure field in a static mixer, as well as the trajectories of particles that are carried by the fluid. In static mixers, a fluid is pumped through a pipe containing stationary mixing blades. For handling fluids, there is combined porous and turbulent media flow as well as infinite elements for media flow with the turbulent two-phase flow. The analysis includes the reflection and transmission spectra, the electric field norm on the top surface of the unit cell, and the dB-scaled electric field norm shown on a vertical cut plane in the unit cell domain. In terms of electrical simulation, you can now model approximated nonlinear magnetic materials in the frequency domain and use shared library files to create magnetic materials. When an ion beam interacts with the higher-density gas, the ions undergo charge exchange reactions with the gas, creating energetic neutral particles. As a consequence, highly energetic ions tend to follow nearly straight paths, whereas less energetic ions follow more random paths.
