• Perform coupling iterations until desired level of convergence – Manual cyclic updates of individual system components

• Option to report assigned volumetric and surface losses in Icepak

Two-way Coupling with HFSS/Maxwell/Q3D


Both surface and volume mapping supported

Icepak – Q3D 2-way coupling


• Automatic system updates using the Feedback Iterator – Automatic cyclic updates of system components until temperatures stop

changing within desired level of tolerance
