MCP server providing ELF600 electromagnetic field analysis (MAGIC/ELFIN/BEAM) documentation: .mai/.mei/.meg formats, eddy current setup (MAB/MAT/MBB), sinusoidal AC (SOL MOMC), IPM motor workflow.

Project description

mcp-server-elf

PyPI License: BSD-3-Clause Python: 3.10+

MCP server providing ELF600 electromagnetic field analysis documentation — file formats, solver options, element types, and workflow recipes for the ELF600 BEM-based electromagnetic analysis suite (MAGIC magnetostatic, ELFIN electrostatic, BEAM particle tracking).

This server does not execute ELF600 simulations — it provides curated documentation that AI coding assistants (Claude Code, Cursor, etc.) can consult while authoring .mai/.mei/.meg input files for ELF.


Features

Single tool: elf_usage(topic) returns documentation on:

  • File formats: .mai (analysis input), .mei (mesh script), .meg (compiled mesh)
  • Solvers: MAGIC (magnetostatic, transient, AC), ELFIN (electrostatic), BEAM (particle tracking)
  • Eddy current: MAB / MAT / MBB elements, time-stepping, sinusoidal AC (SOL MOMC)
  • Element types: full catalog with DOF counts and symmetry restrictions (3D / 2D / Axisym)
  • B-H curves: anisotropy (HBA1/HBA2), recoil, extrapolation
  • IPM motor workflow: Ld/Lq calculation
  • Inductance: Lsc (JIS) and Ll (IEEJ) with 6 samples
  • Magnetization / demagnetization (MAGNE2)
  • Convergence troubleshooting, error codes (160+ ELF-Q/E/W codes)
  • Force methods: FORC vs FORT vs FIXB
  • Tools: IEmesh, Wmap3, MagFilter2, MaiEditor3, ELF/Bench

Available topics:

all, overview, mai_format, mei_format, meg_format,
magic, elfin, beam, element_types, bh_curves,
sol_commands, mei_commands, ipm_motor, inductance,
magnetization, examples, meg_export, treasure_box,
sinusoidal, anisotropy, sted, meshing, convergence,
force_methods, errors, iemesh, tools

Installation

pip install mcp-server-elf

Verify:

mcp-server-elf --selftest

Usage

Claude Code

claude mcp add elf "C:/Program Files/Python312/Scripts/mcp-server-elf.exe"

(Adjust path for your Python install. On Linux/macOS, the script is typically ~/.local/bin/mcp-server-elf or similar.)

Cursor / Other MCP clients

Add to your MCP config:

{
  "mcpServers": {
    "elf": {
      "command": "mcp-server-elf"
    }
  }
}

Self-test

mcp-server-elf --selftest

Iterates through all 26 topics and asserts non-empty documentation.


What is ELF600?

ELF600 is a commercial BEM (Boundary Element Method) electromagnetic analysis suite distributed by Science Solutions International Laboratory (https://www.science-solutions.jp/elf/).

Module Purpose
MAGIC Magnetostatic field (static, transient, AC). Eddy current via MAB/MAT/MBB.
ELFIN Electrostatic field analysis (D-E curves)
BEAM Charged particle beam tracking

Workflow:

.mei (mesh script) --> IEmesh --> .meg (compiled mesh)
.mai (analysis) + .meg --> MAGIC/ELFIN/BEAM --> .mag/.mao results

Why this server?

LLM coding agents authoring ELF input files (.mai/.mei) need access to:

  • The ~60k character ELF reference manual content,
  • Element naming conventions (T/K/R symmetry × element family),
  • SOL block recipes (MOME / MOMC / FIEL / FORC / NONL),
  • Frequency-sweep AC analysis structure,
  • Common error code interpretation,

without polluting context with the entire vendor PDF. This MCP server returns just the relevant topical chunk on demand.
