Issue 11 Electric Field Analysis from A to Z

If you asked many JMAG users how to go about conducting an electric field analysis in JMAG, it's fair to say they wouldn't be able to offer a precise answer immediately. People use JMAG for evaluation of magnetic phenomena, but there are only limited numbers of products that need to make allowances for electric field analyses to it's rare for those involved in magnetic field analyses to reach out to electric field analysis, too. Although the names of electric field analysis and magnetic field analysis have a close resemblance, they're handling different phenomena and are evaluated in a divergent manner. This issue of A to Z will focus on how to handle particular types of phenomena using JMAG's electric field analysis, as well as introduce material properties and various types of conditions so we can get you acquainted with electric field analysis.

Issue 10 Structural Analysis from A to Z

Many JMAG users probably wouldn't have a clear idea of what to do if told to carry out a JMAG structural analysis. Many use JMAG for evaluation of electromagnetic phenomena, but when it comes to structural analysis many confine themselves to only limited uses, such as vibration phenomena. JMAG undoubtedly handles electromagnetic phenomena well, but we'd like to propose linking with heat transfer analysis or structural analysis as expanded functions to heighten analysis precision of those phenomenon. On the other hand, if the phenomena are simple, it's easy to do a good enough evaluation of physical phenomena using just heat transfer analysis or structural analysis. This issue of A to Z will focus on how to handle particular types of phenomena using JMAG's structural analysis, as well as introduce material properties and various types of conditions so we can get you acquainted with structural analysis.

Issue 9 Understanding Thermal from A to Z

There are many people who have the impression that induction heating analysis, thermal demagnetization analysis, and thermal stress analysis are very difficult, aren't there? JMAG thermal analysis handles simple heat conduction phenomena. For this reason, material properties or conditions to be set are less compared with those for magnetic field analysis, so just understanding the meaning of that makes it possible to run an analysis easily. Coupled analyses between thermal and magnetic field, thermal and structural, and thermal and electric field are deceptively difficult, but they are nothing more than extensions of thermal analysis. Consequently, they are not terribly difficult if you can get a firm grasp of the mechanism of thermal analysis.In this issue of AtoZ, I will focus on material properties and various conditions that form the basis of thermal analysis and explain what they are so that you can feel thermal analysis and coupled analysis with heat more familiar.

Issue 8 Understanding Conditions from A to Z

Continuing from last issue, I would like to introduce convenient functions of some of the conditions in JMAG's magnetic field analysis. I hope you will find this useful for finding new conditions and reminding yourself of functions. In this issue, I will present functions to make complicated analysis easy, such as conditions for coupled analysis within JMAG and linked analysis with other software, as well as solver parameters such as nonlinear and ICCG. Why don't you aim at fully mastering JMAG and making your business more efficient?

Issue 7 Understanding Conditions from A to Z

Setting conditions is one job that needs particular attention when doing simulations. Often, when a simulation turns out different from real-world phenomena, or a calculation is run with improper physical conditions set, errors in conditions settings are not found until the calculation results are checked. In order to run accurate simulations efficiently, it is important to know what the conditions mean, and to set physically correct parameters.
In this and the next "A to Z," we will look at conditions that are frequently used in magnetic field analysis, their particular characteristics, and how they are used.

Issue 6 Understanding Geometry Modeling from A to Z

For a simulation which involves an electromagnetic field analysis, it is necessary to create data that represents the geometry of the target model. JMAG can load external CAD file, and can create geometry data for simulations using JMAG-Designer.
This report focuses on "Geometry Creation" and introduces the functions to create geometry data using the Geometry Editor bundled in JMAG-Designer.

Issue 5 Understanding Material Modeling from A to Z

Precise material modeling is one of the factors that can significantly affect the accuracy of a variety of analyses, including electromagnetic field analysis. Most people, however, feel that it requires a lot of time and experience to create precise material modeling that reproduces the behavior of materials by assigning each material property to each analysis objective.
JMAG-Designer has developed material modeling that is not only easy to handle, but can also model the behavior of materials more accurately and easily.
In this issue, I will introduce functions for material modeling in JMAG-Designer that can help make operations more efficient. By all means, use this opportunity to take your modeling abilities to the next level.

Issue 4 Understanding Meshes from A to Z

Most people probably feel that, out of all the operations necessary for a finite element analysis (FEA), mesh generation takes the most time and effort. People tend to worry about mesh generation because it has a big effect on calculation time and accuracy.
JMAG has developed and implemented a variety of mesh generation functions to help reduce the burden on our users. This issue introduces functions for meshes in JMAG that can help make operations more efficient. By all means, take this opportunity to try them out for yourself.
For information about the operating procedures for each function, open Help in JMAG-Designer and look at Home > Analysis > Generating Mesh (Automatic).

Issue 3 Shortening Calculation Time from A to Z

Designers are under constant pressure to meet tight timelines and deliver results as quickly as possible. At the same time, however, they cannot sacrifice accuracy in the pursuit of results. There are also those who worry that a huge amount of calculation time will be required to carry out a large volume of highly accurate calculations.
JMAG has continued to improve its high speed solver functionality and parallel solvers in order to help our customers solve these kinds of obstacles. In this issue, we look at how to shorten calculation time by examining JMAG's functions and introducing methods of creating analysis models. By all means, take this opportunity to try them out for yourself.

Issue 2 Evaluating Results and Viewing Models from A to Z

JMAG supports results evaluations through a variety of post functions. The reason for this is that it reduces the effort that goes into organizing results as much as possible, and we wanted our clients to be able to create shapes for better design proposals quickly.
By all means, use this as an opportunity to take advantage of JMAG's post function, which can multilaterally evaluate and analyze results.

Issue 1 Running Multiple Case Calculations from A to Z

Multiple calculations need to be run simultaneously to examine various designs. Therefore, a repetitive process requiring the same settings be specified over and over, multiple geometrical models with differing dimensions be created, and a large number of analysis results be organized. This repetitive procedure not only costs users time, but also increases the chance of simple mistakes like procedural errors or forgetting to specify settings.
JMAG offers a wide-range of useful features for running calculations with multiple cases to offer users a better design that comes to fruition faster. These features can benefit any user almost immediately.
