Solving Inside or on the Surface

For Maxwell designs, when you assign a material to an object, you can specify whether to generate a field solution inside the object or on the surface of the object. If you elect to generate a solution inside the object, Maxwell will create a mesh inside the object and generate a solution from the mesh. If you elect to generate a solution on the surface of the object, Maxwell will create only a surface mesh for the object.

If you want a solution to be generated inside an object, select Solve Inside in the Properties window. Conversely, if you want a solution to only be generated on the surface of an object, clear the Solve Inside option in the Properties window.

By default, Solve Inside is selected for all objects with a bulk conductivity less than 10⁵ siemens/meter and for perfect insulators. By default, the Solve Inside option in the Properties window is clear for perfect conductors.
