== Domain and Boundary Conditions ==

In EM.Ferma, the Laplace equation is solved subject to boundary conditions. Here, we will discuss how to specify these boundary conditions.
=== 3D Domain ===
[[Image:qsource2.png|thumb|300px200px|The green wireframe around the CAD objects defines the extents of the computational domain. The specified boundary conditions are applied on the domain walls. ]]
EM.Ferma's computational domain defines where the boundary condition will be specified. The domain can be seen as a green cubic wireframe that surrounds all of the CAD objects in the model. To modify the domain boundary, find the "3D Static Domain" entry in the navigation tree, right-click on it, and select "Domain Settings...". The domain dialog will appear. In the domain dialog, the domain boundary can be specified in terms of either a custom, fixed location, or as custom offsets from CAD objects in the scene.
