Article: JMAG 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 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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
