Shield Global Transfer Direction

This keyword is used to set the global transfer direction for all shields. The required input file text line format is:

If the IN parameter was specified, then electromagnetic energy is coupled only from the exterior of shields to the interior. No energy is coupled outward through the shield. In an analogous manner, if the OUT direction was selected, then electromagnetic energy is coupled only from the interior of shields to the exterior. The BOTH selection allows energy coupling in both directions. The BOTH selection is the default direction for all shields.
