Tutorial 1: Application Development

In this tutorial, the reader shall work through the steps to create a custom MOOSE-based application to solve real-world physics problems. The instructions begin with defining the problem and converting the governing partial differential equations (PDEs) into an expression compatible with MOOSE. As the tutorial progresses, the core C++ classes that are available to developers for solving problems, as well as the basic systems of MOOSE, will be discussed.

This tutorial is the focus of the live hosted Framework Workshops. New users are encouraged to engage themselves in this training by reading the content carefully and reproducing the steps, without simply copying and pasting code. This tutorial is designed to be an in-depth explanation of creating a complete, custom multiphysics application including the process of using a repository and testing.
