# Simulation Results Directory Structure

This directory contains results from impact simulations of projectiles on polymeric films. The data is organized hierarchically to represent different simulation parameters.

## Directory Structure

## Parameter Definitions

### Top-level Parameters- **N** : Polymeric chain length (number of monomers per chain)

### Projectile Parameters- **mp** : Projectile mass   - Mass of the impacting projectile  - Example: mp_8000 = projectile mass of 8000 units

### Film Parameters- **H** : Film thickness  - Thickness of the polymeric film

### Derived Parameters- **A** : Mass ratio parameter (alpha)  - Defined as α = mp/(m_film + mp)  - Where:    - mp = projectile mass    - m_film = mass of the polymeric film  - Represents the relative mass ratio between projectile and film

## File DescriptionsEach leaf directory contains:

1. **config2.ini** :    - Simulation configuration file   - Contains all input parameters for the simulation

2. **Impact_R.dat** :   - Impact results data file   - Contains output metrics from the impact simulation:          #timestep: self-explanatory         Tau: simulation time         MR: projectile mass (mp)         RR:projectile radius (rp)         VRi: impact velocity (vi)         VR: projectile velocity during the simulation         kinetic_energy_groupR: kinetic energy of the projectile         potential_energy_groupR: potential energy of the projectile
