# Entropyk CLI
|
||||
|
||||
Command-line interface for batch thermodynamic simulations.
|
||||
|
||||
## Installation
|
||||
|
||||
```bash
|
||||
cargo build --release -p entropyk-cli
|
||||
```
|
||||
|
||||
## Usage
|
||||
|
||||
```bash
|
||||
# Single simulation
|
||||
./target/release/entropyk-cli run config.json -o result.json
|
||||
|
||||
# Batch processing
|
||||
./target/release/entropyk-cli batch ./scenarios/ --parallel 4
|
||||
|
||||
# Validate configuration
|
||||
./target/release/entropyk-cli validate config.json
|
||||
|
||||
# Help
|
||||
./target/release/entropyk-cli --help

## Component Types
|
||||
|
||||
| Type | Required Parameters | Optional Parameters |
|
||||
|------|---------------------|---------------------|
|
||||
| `Compressor` | `fluid`, `speed_rpm`, `displacement_m3` | `efficiency`, `m1-m10` (AHRI 540) |
|
||||
| `HeatExchanger` | `ua`, `hot_fluid`, `cold_fluid`, `hot_t_inlet_c`, `cold_t_inlet_c` | `hot_pressure_bar`, `cold_pressure_bar`, `hot_mass_flow_kg_s`, `cold_mass_flow_kg_s` |
|
||||
| `Condenser` | `ua` | `t_sat_k` |
|
||||
| `CondenserCoil` | `ua` | `t_sat_k` |
|
||||

## Thermal Couplings
|
||||
|
||||
Thermal couplings define heat transfer between circuits:
|
||||
|
||||
```json
|
||||
{
|
||||
"hot_circuit": 0,
|
||||
"cold_circuit": 1,
|
||||
"ua": 5000,
|
||||
"efficiency": 0.95
|
||||
}
|
||||
```
|
||||
|
||||
- `hot_circuit`: Circuit ID providing heat
|
||||
- `cold_circuit`: Circuit ID receiving heat
|
||||
- `ua`: Thermal conductance (W/K)
|
||||
- `efficiency`: Heat exchanger efficiency (0.0-1.0)
|
||||
|
||||
## Solver Strategies
|
||||
|
||||
| Strategy | Description |
|
||||
|----------|-------------|
|
||||
| `newton` | Newton-Raphson solver |
|
||||
| `picard` | Sequential substitution (Picard iteration) |
|
||||
| `fallback` | Picard → Newton fallback (recommended) |
|
||||
|
||||
## Exit Codes
|
||||
|
||||
| Code | Meaning |
|
||||
|------|---------|
|
||||
| 0 | Success |
|
||||
| 1 | Simulation error |
|
||||
| 2 | Configuration error |
|
||||
| 3 | I/O error |
|
||||
|
||||

//! Node - Passive Probe Component
|
||||
//!
|
||||
//! This module provides a passive probe component (0 equations) for extracting
|
||||
//! thermodynamic measurements at any point in a circuit without affecting the
|
||||
//! system of equations.
|
||||
//!
|
||||
//! ## Purpose
|
||||
//!
|
||||
//! The Node component allows you to:
|
||||
//! - Extract superheat after the evaporator
|
||||
//! - Measure subcooling after the condenser
|
||||
//! - Obtain temperature at any point
|
||||
//! - Serve as a junction point in the topology without adding constraints
|
||||
//!
|
||||
//! ## Zero-Equation Design
|
||||
//!
|
||||
//! Unlike other components, `Node` contributes **zero equations** to the solver.
|
||||
//! It only reads values from its inlet port and computes derived quantities
|
||||
//! (superheat, subcooling, quality, phase) using the attached `FluidBackend`.
|
||||
//!
|
||||
//! ## Example
|
||||
//!
|
||||
//! ```ignore
|
||||
//! use entropyk_components::Node;
|
||||
//! use entropyk_fluids::CoolPropBackend;
|
||||
//! use std::sync::Arc;
|
||||
//!
|
||||
//! // Create a probe after the evaporator
|
||||
//! let backend = Arc::new(CoolPropBackend::new());
|
||||
//!
|
||||
//! let probe = Node::new(
|
||||
//! "evaporator_outlet",
|
||||
//! evaporator.outlet_port(),
|
||||
//! compressor.inlet_port(),
|
||||
//! )
|
||||
//! .with_fluid_backend(backend);
|
||||
//!
|
||||
//! // After convergence
|
||||
//! let t_sh = probe.superheat().expect("Should be superheated");
|
||||
//! println!("Superheat: {:.1} K", t_sh);
|
||||
//! ```

//! Intelligent fallback solver implementation.
|
||||
//!
|
||||
//! This module provides the [`FallbackSolver`] which implements an intelligent
|
||||
//! fallback strategy between Newton-Raphson and Sequential Substitution (Picard).
|
||||
//!
|
||||
//! # Strategy
|
||||
//!
|
||||
//! The fallback solver implements the following algorithm:
|
||||
//!
|
||||
//! 1. Start with Newton-Raphson (quadratic convergence)
|
||||
//! 2. If Newton diverges, switch to Picard (more robust)
|
||||
//! 3. If Picard stabilizes (residual < threshold), try returning to Newton
|
||||
//! 4. If max switches reached, stay on current solver permanently
|
||||
//!
|
||||
//! # Features
|
||||
//!
|
||||
//! - Automatic fallback from Newton to Picard on divergence
|
||||
//! - Return to Newton when Picard stabilizes the solution
|
||||
//! - Maximum switch limit to prevent infinite oscillation
|
||||
//! - Time-budgeted solving with graceful degradation (Story 4.5)
|
||||
//! - Smart initialization support (Story 4.6)
|
||||
//! - Multi-circuit convergence criteria (Story 4.7)
