LAMMPS molecular dynamics skill for nanoscale system simulation with force field management

General

What this skill does


# LAMMPS MD Executor

## Purpose

The LAMMPS MD Executor skill provides molecular dynamics simulation capabilities for nanoscale systems, enabling investigation of structural, mechanical, and thermal properties through classical simulations.

## Capabilities

- Force field selection and parameterization
- System equilibration protocols
- NVT/NPT ensemble simulations
- Trajectory analysis
- Thermal conductivity calculation
- Mechanical property simulation

## Usage Guidelines

### MD Simulation Workflow

1. **System Setup**
   - Build initial configuration
   - Assign force field
   - Minimize energy

2. **Equilibration**
   - NVT temperature equilibration
   - NPT for density
   - Monitor equilibration metrics

3. **Production**
   - Run appropriate ensemble
   - Calculate properties on-the-fly
   - Save trajectories

## Process Integration

- Molecular Dynamics Simulation Workflow
- Multiscale Modeling Integration

let-fate-decide

Included

Draws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.
