I have modeled a FLUX-FLUX multi-physics co-simulation e.g. application Steady State AC Magnetic 3D with Transient Thermal 3D,  I do not want to use the magneto-thermal coupling application because it has certain 3D thermal problems with. Someone knows how to pass a parameter in the multiphysics environment between the two apps?, specifically I want  the TIME variable of  transient thermal app accessible into the steady app for change a circuit coupling voltage value,

    Hello,

    In fact, a coupling FLUX-FLUX allows to interchange any spatial quantity between the thermal and the magnetic projects through .DEX files stored in a specific folder usually called “EXCHANGE”.

    In this case, your interest is to send the TIME from the transitory project to the steady state one. Unfortunately, it is not possible to share parameters between applications in a straight way (except spatial quantities).

    I propose you this bypass:  define a spatial variable which value is equal to TIME at any geometrical point. Export this variable from the transient project and import it in the steady state one, where you will be able to read the TIME from any point.

    Best regards,
