# GasModels.jl Documentation

## Overview

GasModels.jl is a Julia/JuMP package for Gas Network Optimization. It provides utilities for parsing and modifying network data (see GasModels Network Data Format for details), and is designed to enable computational evaluation of emerging gas network formulations and algorithms in a common platform. It includes support for steady-state and transient formulations.

The code is engineered to decouple Steady State Problem Specifications (e.g. Gas Flow, Expansion Planning, ...) from Network Formulations (e.g. DWP, CRDWP-relaxation, ...). This enables the definition of a wide variety of gas network formulations and their comparison on common problem specifications.

## Installation

The latest stable release of GasModels is installed using the Julia package manager with

add GasModels

For the current development version, "checkout" this package with

checkout GasModels

At least one optimizer is required for running GasModels. The open-source optimizer Juniper is recommended and can be used to solve a wide variety of the problems and network formulations provided in GasModels. The Juniper optimizer can be installed via the package manager with

add Juniper

Test that the package works by running

test GasModels
