# HYSYS Dynamic Simulator Skill

## Purpose

The HYSYS Dynamic Simulator Skill enables dynamic process simulation for transient analysis, control system design, and emergency scenario evaluation.

## Capabilities

- Dynamic process simulation
- Pressure-flow solver configuration
- Controller tuning with dynamics
- Compressible flow analysis
- Transient scenario analysis
- Emergency shutdown simulation
- Trip system verification
- Batch process modeling

## Usage Guidelines

### When to Use
- Analyzing transient behavior
- Designing control systems
- Evaluating emergency scenarios
- Validating trip systems

### Prerequisites
- Steady-state simulation complete
- Equipment volumes defined
- Control strategy established
- Scenario requirements identified

### Best Practices
- Start from converged steady-state
- Define appropriate time steps
- Validate against plant data
- Document scenario assumptions

## Process Integration

This skill integrates with:
- Process Simulation Model Development
- Control Strategy Development
- Process Startup Procedure Development

## Configuration

```yaml
hysys-dynamic-simulator:
  solver-modes:
    - implicit
    - explicit
  scenario-types:
    - startup
    - shutdown
    - emergency
    - load-change
```

## Output Artifacts
