What is the difference between MD3SCRGDV MD3SCRHJ, MD3SCRT0W formulations?

Yann_Le_Floch

All these formulations are used in applications with circuit coupling. However they define different types of regions. The MD3SCRGDV formulation is used to define magnetic non conducting regions composed of non linear magnetic materials. The formulations MD3SCRHJ and MD3SCRT0W are used to define air regions. Both formulations have the same functionality, but the mathematical computation is different. Furthermore, MD3SCRHJ seems more appropriate in projects that contain small air gaps.
