ENGINEERING SCOPE AND LIMITS
This release covers radial-flux PMSM studies, not the separate AFPM product. Commercial availability does not imply qualification for every geometry or operating point. Consult the supplied validation report, check convergence and material data, and retain case-specific engineering review. Local AC winding-loss studies do not represent total machine loss; they exclude adjacent tooth iron, end turns and circulating strand currents. Operating-map and specialist export limitations remain applicable.
ANALYSIS CAPABILITIES
From geometry to fields, waveforms, harmonics and torque.
Machine construction, Netgen meshing and separately installed Elmer solving are connected within the EM3 workflow.
Nonlinear finite-element solution
Two-dimensional magnetic vector-potential analysis includes nonlinear steel, permanent magnets and controlled material assignment.
Controlled conformal mesh
Air-gap radial layers, tooth-tip detail, magnet edges and refinement controls preserve the geometry needed for field and torque extraction.
Static and transient studies
Open-circuit, loaded and rotating-machine transient calculations support electrical-angle stepping and repeatable comparison.
Field and harmonic evidence
Radial and tangential air-gap fields, spatial and temporal spectra, B magnitude and vector-potential contours are available for review.
Results and exports
Inspect flux linkage, phase and line back EMF, cogging and loaded torque. Export numerical CSV, field plots and complete full-machine 2D geometry DXF.
PACKAGE REVISION 3 · PUBLISHED 7 OCTOBER 2026
Includes clearer notices when edited inputs invalidate displayed results, a Documentation shortcut and preservation of a configured qualified Elmer location during upgrade. Five PDF volumes with LaTeX sources cover the user manual, reference manual, material database, validation report and development chronicle. Numerical qualification remains bounded by the retained evidence; this packaging revision does not introduce a new accuracy claim.
ONE ELECTRICAL CYCLE · 6° ELECTRICAL STEPS
Field evolution made visible.
Fixed colour scales and dark geometry outlines allow each frame to be compared directly through the full electrical cycle.
Magnetic flux-density magnitude
Nonlinear B magnitude is animated with a fixed 0 to 1.959 T scale.
Magnetic vector potential
Signed vector potential and field lines are animated on a fixed ±0.01060 Wb/m scale.
HISTORICAL TRI135 DEVELOPMENT EVIDENCE
Geometry fidelity and solver correlation are reviewed together.
The retained animations and plots illustrate the earlier controlled Tri135 development comparison. They are not a new Netgen-versus-Gmsh qualification of this installer, or a universal accuracy guarantee. Use the supplied validation report for the release evidence and its limitations.
Four-layer transient sliding mesh
The Tri135 transient solver uses two rotor-side layers and two stator-side layers meeting at the disconnected physical mid-gap sliding interface.

Three-way open-circuit comparison
EM3 static, EM3 transient and Motor-CAD flux-linkage and back-EMF waveforms are compared on one governed basis.
View full resolution ↗At 3000 rpm, this historical Tri135 open-circuit back-EMF fundamental comparison recorded 189.41 V RMS for EM3 static, 189.48 V RMS for EM3 transient and 189.71 V RMS for Motor-CAD.
