Select and configure nonlinear solvers for root-finding f(x)=0, optimization min F(x), and least-squares problems — choose among Newton, Newton-Krylov, quasi-Newton (BFGS, L-BFGS), Broyden, Anderson acceleration, and Levenberg-Marquardt methods, configure line search or trust-region globalization, diagnose convergence rate (quadratic, linear, stagnated), and assess Jacobian quality and conditioning. Use when a Newton solver converges slowly or diverges, choosing between line search and trust re…

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'nonlinear-solvers' ] || [ -L ~/.agents/skills/'nonlinear-solvers' ]; then echo 'A skill folder named nonlinear-solvers already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/HeshamFS/materials-simulation-skills' "$d" && git -C "$d" checkout --quiet '775055956bb8fa3838032c49a346e26d94d0d1f6' -- 'skills/core-numerical/nonlinear-solvers' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/core-numerical/nonlinear-solvers' ~/.agents/skills/'nonlinear-solvers' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'nonlinear-solvers' ~/.claude/skills/'nonlinear-solvers' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
