A main program of JMAG.
From creating geometry to result analysis, this module can run everything except for calculation. It includes convenient tools such as the Geometry Editor, automatic mesh generation, and analysis templates.
In addition, it also features application functions such as parametric analysis, optimization functions, and the motor characteristic evaluation tool JMAG-Express.
ST Magnetic field static analysis (2D, 3D, axisymmetric)
Can be applied when magnetomotive forces such as electric currents and model motion do not change over time. Cross-section analysis of magnetic field static analysis is also included.
Linear and non-linear material can be handled.
Magnetic field/magnetization/magnetic flux/magnetic flux density/current/vector potential/coercive force/magnetization ratio/torque/electromagnetic force/Lorentz force/permeance coefficient, etc.
TR Magnetic field transient analysis (3D)
3D analysis can be run when magnetomotive forces such as electric currents and model motion change over time.
Non-linear material can be accurately handled.
Rotation motion and translation motion can also be handled.
Magnetic field/magnetization/magnetic flux/magnetic flux density/current/current density/vector potential/coercive force/magnetization ratio/torque/electromagnetic force/stored energy/Lorentz force/voltage/current/permeance coefficient/displacement/eddy current density/eddy current loss, etc.
FQ Magnetic field frequency analysis (2D, 3D, axisymmetric)
Magnetic field analysis can be run when there is sinusoidal change in magnetomotive forces such as electric currents. This includes cross-section analysis of magnetic field frequency analysis.
Material characteristics are assumed to be linear, but by applying nonlinear data it is possible to run analysis that accounts for approximate nonlinearity analysis and hysteresis loops.
Magnetic field/magnetization/magnetic flux/magnetic flux density/current/current density/vector potential/torque/electromagnetic force/stored energy/Lorentz force/eddy current loss/current/voltage, etc.
DP Magnetic field transient analysis (2D, axisymmetric)
2D magnetic field analysis can be run when the target subject changes over time, such as the analysis of the magnetomotive force of electric currents, and model motion.
When using FEM and BEM together, mesh generation in air regions is not required.
Materials and motion can be handled in the same way as in 3D analysis.
This license is also used for transformer analysis depending on the settings.

HT Thermal analysis (3D)
Both the “steady state analysis” and “transient state analysis” can be run for thermal analysis.
In a “steady state analysis”, there is no time variable in temperature distribution whereas in a “transient state analysis”, the transient state is analyzed until the temperature distribution reaches a steady state.
It is structured to account for coupled analysis with magnetic field analysis modules, making it easy to run coupled analysis by entering losses, obtained from JMAG magnetic field analysis and electric field analysis.
Temperature/heat flux/contact thermal resistance/heat transfer coefficient/displacement, etc.
EL Electric field analysis (3D)
The following electric field analysis can be run: “static analysis”, “frequency analysis”, and “current distribution analysis”.
“Static analysis” analyzes in a state where there is no change in electric charge and potential. “Frequency analysis” analyzes electric potential when there is sinusoidal change over time in electric potential. “Current distribution analysis” obtains current distribution in conductors determined by electrical conductivity and electrical potential.
Electric field/normal electric field/electromagnetic force/current density/dielectric loss/surface charge density, etc.
DS Structural analysis (2D, 3D)
The following structural analysis can be run:
“eigenmode analysis”, “static analysis”, and “frequency analysis”.
“Eigenmode analysis” obtains eigenvalue determined by the geometry and stiffness of the structure. “Static analysis” obtains displacement and stress affected by static load with no time variation. “Frequency analysis” obtains the response of the structure in steady state vibration.
“Transient analysis” can also be run, where electromagnetic force obtained from magnetic field analysis and temperature obtained from thermal analysis are accounted for as load.
Displacement/acceleration/stress/strain/plastic strain/sound pressure/eigenmode, etc.
LS Iron loss analysis
Iron loss can be calculated based on the calculation results of magnetic flux density, etc., in magnetic field analysis.
Iron loss analysis by the iron loss analysis solver uses the results of magnetic field analysis. Therefore, any one of the solver licenses (ST, TR, DP, FQ) for magnetic field analysis is required.
Iron loss/hysteresis loss/Joule loss/anomalous eddy current loss/classical eddy current loss, etc.
CB Field integral calculation
With this tool, the magnetization vector, current density, beam current, and load data included in magnetic field analysis and electric field analysis results can be used to calculate the magnetic flux density and electric fields of a specified location (in air) using the integral method.
To use this tool, result files output by using the magnetic field analysis solver license (DP, TR, FQ, ST) or the electric field analysis license (EL) is required.
Magnetic flux density/electric field
RT Plant model generation tool for circuit/control simulator
In JMAG FEM analysis, the calculation results of motor characteristics accounting for magnetic saturation can be output in a circuit/control simulator dedicated file format (*.rtt). This allows for fast circuit/control simulation that accounts for motor characteristics.
In addition, the torque-speed curve of the JMAG-RT model can be created and displayed using JMAG-RT Viewer.

PI Bus bar inductance calculation
This is a tool to calculate the self-inductance and mutual inductance of conductors using magnetic field analysis or current distribution analysis JCF files.
This tool requires an input file created with the magnetic field analysis solver license (FQ) or the electric field analysis solver license (EL).
Partial inductance/total inductance/resistance
PA2 Parallel processing (shared memory multiprocessing type SMP), massively parallel processing type (MPP), hybrid type (SMP+MPP))
Shared memory multiprocessing type (SMP) and massively parallel processing type (MPP) can be used. Solutions can be obtained faster by the parallel processing of clusters and cloud computing from the desktop. Note that this includes the use of the GPU (Graphics Processing Unit) in the previous GPU solver.

JMAG-RT Viewer can be used to draw efficiency maps based on RTT files.

TS Transformer analysis
Transformer analysis focuses on running electromagnetic field analysis for transformers, reactors, and inductors
3D analysis models can be created by selecting the core, bobbin, or winding. In addition, these analysis model can be used to run high-speed analysis including Litz wire accounting for the skin/proximity effects of winding loss.
Transformer analysis requires one of the magnetic field analysis solver licenses (TR, DP, FQ) because the analysis type is automatically selected depending on the settings.
