How to install the core-numerical plugin
Run both commands inside Claude Code. The first adds the marketplace once; the second installs the plugin.
/plugin marketplace add HeshamFS/materials-simulation-skills
/plugin install core-numerical@materials-simulation-skillsWhat's inside core-numerical
8 parts read from the plugin's own files.

Claude loads it when the task matches- convergence-study
Performs spatial and temporal convergence analysis using Richardson extrapolation and Grid Convergence Index (GCI) calculations.
- differentiation-schemes
Select and apply numerical differentiation schemes for PDE and ODE discretization, including stencil generation and truncation error estimation.
- linear-solvers
Selects and configures linear solvers for Ax=b systems, analyzes matrix conditioning, and diagnoses convergence issues in numerical simulations.
- mesh-generation
Plan and evaluate mesh resolution and quality for numerical simulations using physics-based scaling and geometric metrics.
- nonlinear-solvers
Selects and configures nonlinear solvers for root-finding, optimization, and least-squares problems while diagnosing convergence and Jacobian quality.
- numerical-integration
Selects and configures time integration methods for ODE and PDE simulations, including adaptive step-size control and IMEX operator splitting.
- numerical-stability
Analyzes numerical stability for time-dependent PDE simulations using CFL, Fourier, and von Neumann criteria to recommend time-stepping schemes.
- time-stepping
Plan and control time-step policies, output intervals, and checkpoint cadences for transient simulations to ensure stability and minimize lost work.
Using core-numerical in Claude Code
Skills need no command. Claude reads them when your request matches what they describe.
