Chronos

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.

  • Permittivity, permeability and conductivity data stored in convenient and rapidly accessible tables

Solvers and Meshing

  • INTEGRATED includes the most appropriate solvers for every kind of application: different solvers accomplish different tasks in different ways.
  • CHRONOS has the capability to handle high frequency problems and certain types of low frequency problems, e.g. lightning problems. FIR filter will be applied for low frequency problems at each time step to filter the high frequency errors.
  • Uniform or non-uniform meshing.
  • Refining the mesh automatically as well as optional local and global user mesh refinements.
  • Conformal Finite Difference Time Domain.
  • PML, PEC and PMC boundary conditions.

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.

3D Programs:

  • The programs will run with a minimum of 4 GB of RAM but this is not recommended for larger problems in which 12 GB of RAM or more should be used. The more RAM used, the faster larger problems will be solved
  • Multi-core processors are strongly recommended as the 3D programs are multi-threaded

INTEGRATED supports software products for 64 bit operating systems

For most of our customers, this announcement has no relevance as most companies have standardized hardware requirements that fit or exceed the 64 bit operating systems required by our company. INTEGRATED’s development tools used for advancements require the installation of 64 bit systems*.

Experience the full power of our simulation tools. Automatically reduce the solution time.

By running the software in a 64 bit system, the system is able to make more effective use of available RAM. The performance of the simulation is greatly affected by the power of the computer in use.

*The suppliers of the software tools we use have this requirement for us as well.

Available RAM versus Problem Size

For small problems the processor speed is the biggest consideration for calculations. If your processor works at twice the speed the problem will be solved in half the time. For larger problems, however, memory management progressively becomes a bigger and bigger consideration. If the memory needed to solve is larger than available RAM – then most of the problem is being swapped back and forth between RAM and the hard disk as the problem proceeds. The efficiency of this process becomes the biggest single factor in the speed of solving large problems. Since this is managed by Windows itself – taking account of other processes also running – we can do very little to help you optimize further from within our software, but can offer the following advice regarding the system setup:

  • Determine the size of problems you will be solving. This is reported in the Message Area as required disk space when the BEM solver begins. It is also reported for the existing element distribution from the menu Solution>Elements>Problem Size.
  • The importance of getting as much RAM as needed on a 64 bit system is illustrated by the benchmark results below for a challenging magnetic problem run on 4 different computers:
    Comparising of solution times for a nonlinear 3D magnetic model requiring 6 GB memory

    The model took 6 hours to solve on a basic system and 3/4 hour to solve on a good system. There are many differences between the 4 systems used, leading to some noise in the plot. However, it is clear that the optimal solution is to use a 64 bit version of the software with more RAM available than the reported memory requirement.
  • 2 hard drives: When choosing hard disk features access time is clearly important. You can set up the locations of the scratch files from Utilities>Settings. Out of various configurations we tested, this was the single most important factor in performing faster analyses when the memory required exceeded available RAM.
  • RAID ARRAY: using a RAID array lets you use multiple disks as a single drive letter, but will manage the access very efficiently. We configure our own systems such that IES software is installed on d: (a RAID array) with the program and scratch files using d:. For more generic information about configuring a RAID array on your computer, check HOW TO: Establish a Striped Volume (RAID 0) in Windows Server 2003 (Microsoft Knowledge Base).
