JAX 3D Modal Analysis

What it does

JAX 3D Modal Analysis provides a reproducible pipeline to perform full 3D tetrahedral finite-element modal analysis on membrane and ribbed resonator geometries. Given a binary STL and material properties JSON, it repairs the surface mesh, generates a tetrahedral volume mesh (TetGen), assembles stiffness and mass matrices using JAX-enabled FEM tooling, and solves the generalized eigenvalue problem to report eigenfrequencies and mode shapes.

When to use it

Use this skill when you need high-fidelity modal analysis that accounts for volumetric effects, frame stiffness, and out-of-plane deformation—typically for validation after a fast 2D screening. It's suited for ribbed or curved membranes where 2D approximations are insufficient.

What's included

• Scripts: executable pipeline scripts in scripts/ (has_scripts=true) to run the solver and produce JSON, PNG, and CSV artifacts.
• References: usage examples and argument documentation are embedded in the SKILL.md; no separate references/ directory.
• Instructions: command-line usage with flags for STL path, material JSON, solver backend, mesh scale, number of modes, and output directory; outputs include eigenfrequency lists, mode counts in range, and paths to summary PNG/CSV.

Compatible agents

Best used by agents capable of running Python and scientific toolchains (JAX, TetGen, meshio). Agents that can orchestrate conda/envs and long-running numeric jobs will get the most value.
