PDEModels Overview
This notebook, in contrast, provides an overview over which fields of physics have a high level representation in the Wolfram Language. The various fields presented here have a varying degree of completeness. Again, if a specific equation is not presented here it does not mean that it can not be solved, it just means there is no high level representation yet. Future versions of the Wolfram language will continue to expand in this area.
Typically, a field of physics that is considered complete consists of a guide page specific to that area, one or more monographs explaining the theory behind the functions provided. In some cases verification notebooks are provided. A collection on models provides extended examples that showcase a specific application. The application models are typically more extensive then what one would normally find in the reference documentation. The example collection points to examples from the reference documentation that show a feature of particular interest.
The PDEs and boundary conditions guide page of a specific field of physics will link to a guide page that provides a listing of all available PDE functions and boundary conditions that are useful for creating PDE models in that area. A short description of the various PDE models can also be found on the guide page and a more detailed overview of which model makes use of which functionality is provided last.

The Finite Element Method
The finite element method is a solution method for partial differential equations and the main method to solve the PDE models presented here. More information on the finite element method is found in the following guide and overview page.
