CHRONOS ——CHRONOS 三维有限差分时域求解器

CHRONOS为设计者提供了最强大的创新技术,包括时域有限差分法(FDTD),矩量法(MOM)和有限元法(FEM)。

CHRONOS的界面易于使用,允许专业人士模拟几何和分配物理特性,在时域中提供快速和准确的结果。在CHRONOS中通过强大的后处理工具,时间域的结果可以转换并且通过在频率域上的不同的参数来展示。

CHRONOS具有智能网格生成器代码的功能,能够识别任何结构的所有细节,并根据算法的精度要求决定如何分发网格。这样给了用户两个选项,要么手动生成网格分布,要么通过使用非均匀的智能网格生成器自动生成。智能网格生成器用来提高解决方案的准确性,并减少计算域中的单元数,从而大大提高使用的内存和速度。


主要特点

3D RF和微波场求解器在各种领域的应用。

时域有限差求解器。

CHRONOS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”。

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

 

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。


By adding CHRONOS to its product line, INTEGRATED will provide designers with the most powerful innovative techniques including: Finite Difference Time Domain (FDTD), Method of Moments (MoM), and the Finite Element Method (FEM).

The easy-to-use interface of CHRONOS allows professionals to model the geometry and assign physical properties, providing fast and accurate results in the time domain. The time domain results can be transformed and displayed with different parameters in the frequency domain through the powerful automatic post processing tools in CHRONOS.

CHRONOS also has a smart mesh generator code with the ability to recognize all the details of any structure and decide how to distribute the mesh based on accuracy requirements of the algorithm. This gives the user two options, to either generate the mesh distribution manually, or automatically through the use of non-uniform smart mesh generator. The smart mesh generator is used to improve the accuracy of a solution and to reduce the number of cells used in the computational domain, leading to a significant improvement in the used memory and speed.

Key Features

·        3D RF and microwave field solver for a diverse range of applications.

·        Finite difference time domain solver.

·        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.

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.
