LORENTZ ——带电粒子轨迹求解器

LORENTZ CAE软件套件为2D/RS和3D带电粒子轨迹分析提供复杂的仿真和定制设计工具。LORENTZ的各种应用包括对阱中粒子运动的研究,如Penning阱或粒子通过光学元件的路径,如弯曲磁铁和多聚焦磁铁或带梁的形状,如双栅离子枪。LORENTZ用于解决电场和磁场的求解,这些求解器经过几十年的应用已经证明了它的可靠性,如各种电机设计,天线以及高压输电线路。

根据配合的场求解器,LORENTZ可应用于electric(E),magnetic(M)或者综合2D和3D中的分析(EM),也就是 LORENTZ-2E, LORENTZ-2M, LORENTZ-2EM, LORENTZ-3E, 

LORENTZ-3M以及 LORENTZ-3EM。如果有更高频率的需求,可以选择LORENTZ-HF。INTEGRATED的参数和批量处理工具可以用来自动运行LORENTZ模型,如优化设计和耐受性测试。由于我们程序中的并行功能,处理速度无疑是设计师们选择光线分析和粒子轨迹软件的一个重要优势。


主要特点

应用于各种2D/RS和3D带电粒子轨迹场求解器中。

LORENTZ三维程序包中的光(束)轴为光线分析提供了便捷的参考信息。

准瞬态模式对不同时间的依赖,在不同的时间重建场比完全暂态快的多。

LORENTZ软件包包括:

. Choice of solvers:为了确保您对解决方案和独立验证的信心,边界元法和有限元方法都包含在同一个软件包中,以满足您的特定应用需求。不是每一个求解器都适合每一个应用程序,没有“万用求解器”。

. Choice of optimization tools:参数分析是为那些需要利用短期学习曲线而达到快速和简单优化的用户服务的。API和脚本给予高级用户更多的权限。这两种工具包含在同一个软件包中。

. Built-in material libraries: 为了方便您访问需要使用的材料,可以自定义和创建自己的库。

. Integration with MATLAB: 用户的MATLAB代码可以调用API函数,建立几何、分配物理参数、求解并得到结果。

. Parallelization: 当使用64位电脑时,允许充分利用可用的RAM来提高解决方案和后处理的速度。

直观的界面,可以更容易地根据用户的喜好定制(整体外观、工具栏、求解器、背景、默认等)。

系统需求

64-bit操作系统

Microsoft Windows Vista , Windows 7, Windows 8或更高版本

软件安装大约需要110MB的磁盘空间

 

2D程序

至少4GB的内存

虽然软件运行在单处理器的机器上,但运行在多处理器系统上时,将允许软件利用并行资源进行并行求解。

 

3D程序

至少4GB的内存,如果处理更大问题时,将占用12GB以上的内存;占用内存越多,处理的速度越快。

由于3D程序是多线程的,所以建议使用多核处理器电脑。

 

 



INTEGRATED’s LORENTZ suite of CAE programs provide sophisticated simulation and design tools customized for charged particle trajectory analysis in 2D/RS and 3D. The diverse applications of LORENTZ include studying the motion of particles in traps such as a Penning trap, or the paths of particles through optical components such as bending magnet and multiple focusing magnets, or the behavior of beams such as the dual grid ion gun.

LORENTZ is available in combination with INTEGRATED’s well-established electric and magnetic field solvers. These solvers have proven their reliability over decades of use in applications as diverse as motor design, antennas, and high voltage transmission lines. Depending on the accompanying field solvers, several varieties of LORENTZ programs are available for applications involving electric(E), magnetic(M) or combined ?eld analysis(EM) in 2D and 3D known as LORENTZ-2ELORENTZ-2MLORENTZ-2EMLORENTZ-3ELORENTZ-3M andLORENTZ-3EM.

For the high frequency option, please choose LORENTZ-HF.

INTEGRATED’s Parametric and batch utilities may be used to run automatic variations on the LORENTZ model for purposes such as design optimization or tolerance testing.

Learn about LORENTZ Solver Methods and our Specialized Beam Analysis Physics Options.

Thanks to the parallelization of our programs (included in our packages at no extra cost) the solution speed is certainly a major benefit for designers requiring beam analysis and particle trajectory software.

Key Features

·        2D/RS and 3D charged particle trajectory field solver for a diverse range of applications.

·        Optical (beam) axis in the 3D package to provide a convenient reference for analyzing a beam.

·        Quasi-transient mode that rebuilds the field at different times for arbitrary time dependencies, which is much faster than doing a full transient solution.

·        At no extra cost, our software packages include:

·        Choice of solvers: To ensure you have confidence in the solution and for independent verification, both BEM and FEM methods are included in the same software package to suit your specific application needs. Not every solver fits every application, no “one size fits all”.

·        Choice of optimization tools: Parametric Analysis for those who need fast and easy optimization with a short learning curve. API and Scripting give more power to advanced users. Both tools are available in the same package.

·        Built-in material libraries: Customize and create your own library for easy access to the materials you use.

·        Integration with MATLAB?: Users’ MATLAB code can include function calls to the INTEGRATED API to build geometry, assign physical parameters, solve, and obtain results.

·        Parallelization: When used on 64-bit computers, this permits full utilization of the available RAM to dramatically increase speed of solution and post-processing.

·        Intuitive interface that can be easily customized according to user preferences (overall appearance, toolbars, solvers, backgrounds, defaults, etc).

Analysis

·        Multithreading makes the electric and/or magnetic solution is faster, with the speed proportional to the number of processor cores on the computer.

·        Simultaneous ray tracing can be used when solving for a beam with multiple rays where each processor core is computing one ray at a time.

·        Periodicity and symmetry features minimize modeling and solution time.

·        Import electric and/or magnetic fields from other simulation software, theoretical predictions or physical measurements.

·        Choice of algorithms for calculating trajectories.

·        DC or time dependent magnetic and electric fields.

·        Beam analysis enables the user to include the effects of space charge in the beam.

·        Space charge can be calculated by element or “tube” methods.

·        Capable of handling several current emission regimes, such us Fowler-Nordheim, Child’s Law and Richardson-Dushman, among others.

·        Calculates a beam’s emittance.

·        Statistical treatment of secondary emitters.

·        Mechanical forces allow the effects of gravity or any Stokes’ force on a particle with a defined radius to be analyzed. For example, a water droplet can be examined with the effects of air (including wind), rather than in a perfect vacuum.

·        Characteristic Mobility Coefficient, rather than a Stokes’ force based calculation, calculates particle velocity using mobility, greatly accelerating the calculation process.

·        Capable of handling multiple emitters, collectors and particle beams.

·        Classical or relativistic modes.

Solvers and Meshing

·        INTEGRATED includes the most appropriate solvers for every kind of application.

·        Both BEM and FEM solvers are included in the same software package, at no extra cost, to suit your specific application needs.

·        Auto solver will choose FEM or BEM based on the general nature of a model (either can still be manually selected).

·        Self-adaptive meshing and optional user refinement.

·        User assigned weighting factors: Inform the solver of areas that interest you so the that the local results are refined.

·        Periodic and symmetry features minimize modeling and solution time.

Optimization

·        At no extra cost, INTEGRATED includes a variety of optimization tools in the same software package so that you can find one that best suits your particular design: Parametric Analysis, Scripting and API. Parametric Analysis works best for those who need fast and easy optimization with a short learning curve while API and scripting give more power to advanced users.

·         

·        The parametric feature allows a definition of variable parameters to be stepped through for the analysis of multiple “what-if” scenarios and facilitating design optimization.

·        Scripting: Virtually unlimited ability to explore design variations.

API

·        Create your own applications: Write your own dedicated tools for specific tasks. Users can program and have full control of their custom electromagnetic application, while using INTEGRATED programs in the background.

·        INTEGRATED’s API allows a variety of programs such as MATLAB, Excel, and Microsoft Visual Studio to work with our software in an interconnected environment. Other software tools can be used with our API in the same way.

·        Add-on utility tools: Select among our custom mini-programs to enhance your design capabilities.

·        Users with programming and/or scripting skills will find this is a very powerful tool.

Materials Table

·        Several material tables provide many integrated libraries. Customize and create your own library for easy access to the materials you use.

Analyzing Your Results

·        Audiovisual (AVI) files allow you to show the results in an animation.

·        A variety of display forms for plotting results, including scalar and vector field quantities such as graphs, contour, arrow, streamline, scatter and vector loci plots.

·        High quality graphics and text utility for preparation of reports and presentations.

·        Data exportable to formatted files for integration with spreadsheets and other software packages.

·        Wide array of post processing options for design evaluation and optimization.

·        Efficient use of parallel processing for post-processing operations.
