External

External interactions model the effect of external fields on the system. They are also used to apply boundary constraints to the system, such planes, spheres …

Regarding the external fields, there are several options, some of then are derived from an analytical expression while others are derived from tabulated data.

The following is a list of the available external interactions:

• ConstantForce
• ConstantTorque
• SphericalShell
• Plates
• ExternalTabulated
• PolarizationTabulated
• ConstantMagneticField
