Graph

Changes in each physical quantity and relationships are grasped and can be evaluated.
Further, it is possible to compare with different analysis results and create a graph that combines (lissajous) different physical quantities.

User Components

User components are a feature that runs user-defined calculations in the post-processing for physical quantities obtained in a JMAG analysis. The analysis results can be evaluated based on the criteria the users would like to focus, such as the physical quantities after running four arithmetic operations that have been defined, or displaying the maximum/minimum of all the steps for the hysteresis using a contour plot.

Cut Plane Display

It can handle the physical phenomena that occur inside of an appliance because it is a simulation.
With JMAG, by creating cut-plane of the model in a location of your choosing, you can confirm results in parts that you cannot see. There are two types of cut planes: A "Cut Plane," which you can create as you wish, and a "Cylindrical Plane," which creates a plane of the cylindrical area. It is also possible to use them in combination. It is easy to switch between hiding and displaying the cut plane, and to display it by itself, as well.
The steps for creating a cut plane are as follows:

  1. Right-click on [Cut Planes] under [Model] in the [Treeview] tab.
  2. Click on [New Cut Plane].
  3. Enter a title, specify a location for the cut plane, select a display type, and click [OK].
