What is Q3D simulation

Ansys Q3D Extractor is a 3D quasi-static electromagnetic simulation software tool and lumped RLC parameter extractor.  It calculates fields, inductances, resistances, and capacitances. This tools that specializes in low-frequency power applications. It can quickly determine parasitic values of inductance, capacitance, resistance from 3D structures.Q3D can generate frequency dependent equivalent circuit netlists in many formats.

It provides automatic, accurate, and efficietn solution after refining the mesh throughout structure.
