[[Image:fermbc.png|thumb|200px|Boundary Condition Dialog]]
EM.Ferma allows the user to either specify the potential on the boundary (Dirichlet boundary condition), or specify the normal derivative on the boundary (Neumann boundary condition) via a specified field strength. To modify the boundary condition, find "Boundary Conditions" on the navigation tree, and select "Boundary Conditions...". The user will be prompted with the dialog seen in figure.
