JMAG Version 10.0

- Using JMAG as a Design and Evaluation Tool -

JMAG for Designing and Evaluating Devices

JMAG ver. 10 was released on June 8, 2009. This version of JMAG has been developed with a focus on streamlining the workflow required to perform analyses. The speed with which an analysis can be performed is vital when designing and evaluating results. A vast amount of designs need to be evaluated by editing dimensions to attain the highest level of quality. This means that the number of designs that can be evaluated is directly connected to the quality of the design. New and improved functions have been implemented into JMAG ver. 10 to provide the most efficient design and evaluation process. This article introduces the major functions version 10 has to offer, that include but are not limited to, parametric analyses, analysis templates, as well as a scripting function.

Investigating a Multitude of Designs with Parametric Analyses

Investigating the effects of design variables on the performance of a device is a vital part of the design and evaluation process. A multitude of varialbes can be simulated in JMAG by running a series of analyses that encompass a wide range of parameters (parametric analysis).

A series of operations for the parametric analyses can be performed directly from the general users interface in JMAG-Designer ver. 10. Variables for a parameter analysis can be selected by displaying a list of settings from the dimensions of the geometry to the settings specified to generate the mesh. The data for each case is automatically generated for a range of variables specified for a setting. Furthermore, the geometry of a model can be edited and displayed easily by simply moving a slider bar.

The analysis results need to be evaluated after multiple cases are evaluated with a parametric analysis. Generally, a response graph is drawn with the variables on the vertical axis and the output on the horizontal axis, but the same response graph can be generated easily in JMAG-Designer ver. 10.

Standardizing Analyses with Analysis Templates

Knowledge about the material and condition settings required for an analysis is not the same as the knowledge required to design and evaluate a device. For this reason, standardizing the knowledge required to perform an analyses is vital.

Therefore, a new analysis template function has been added to JMAG-Designer v10. An analysis template saves all of the settings, except for geometry, used to perform an analysis. These settings, such as materials, conditions, and analysis result settings, are saved when a template is exported from one model and then imported for another model. Analysis templates provide an invaluable educational tool that can be used to efficiently pass on the knowledge acquired by an experienced user to a novice user.

Automating the Analysis Process with Scripts

The analysis process in JMAG can be automated by standardizing settings that are often specified to evaluate designs with an analysis. These operations can be automated by writing and executing operations with a script.

JMAG-Designer supports VBscript, JScript, Python, and universal script languages which are compatible when linking to another analysis system. In addition, a function to record script commands while operations are performed has been implemented into JMAG-Designer ver. 10.
The functions that have been introduced above focus on the design and evaluation process. In the sections that follow lets look at the new and improved modeling and analysis functions.
