Advanced Electromagnetic Modeling

Powerful Finite Element Method solver for electromagnetic simulations

Nabla provides cutting-edge computational tools for analyzing complex low frequency domain electromagnetic phenomena with high accuracy and efficiency. Perfect for engineers, researchers, and scientists.

Key Capabilities

Magnetostatic, Time-Harmonic & Transient Solvers

Static, time-harmonic and step-by-step transient 2D magnetics, planar or axisymmetric, with first- and second-order (P2) elements

Motion Without Remeshing

Rotary and linear motion via a sliding band, including multiple simultaneous zones — two rotors, a rotor and a linear mover, or a magnetic gear — with no mesh distortion

Circuit-Coupled Simulation

Field-circuit coupled solves with R, L, C, sources and switches, wired directly to coils and squirrel-cage rotor bars

Thermal Module

Steady-state and transient heat conduction on the same mesh, driven by the field solution's own Joule and iron losses

Nonlinear & Anisotropic Materials

BH-curve saturation, permanent-magnet demagnetisation risk, and anisotropic permeability for laminated and oriented steel

Python API & MCP Automation

Drive Nabla headlessly for parametric sweeps and batch studies, or let an LLM build and run models through the MCP server

Applications

Motor Analysis

Design and analyze electric motors and generators

Electromagnetic Devices

Simulate transformers, inductors, and other EM devices

Linear Motors

Model linear motor systems for transportation and automation

Example Library

Eight ready-to-open machine models ship with Nabla — surface-magnet, spoke, Halbach, buried V-magnet and outrunner PMSMs, and squirrel-cage induction machines with skewed rotor bars. Each one is rebuilt from nothing by the Python script beside it, and each publishes the results, figures and PDF report that run produced.
