[Getdp] TR: Using H-Phi form. Case of an inductor (axisymmetric 2D model)

[Geoffrey LOSSA UNEN]

Dear Getdp member,

Is it possible to use cohomology functions for a 2D model of an inductor with massive conductors in case of H-Phi formulatiion?
If yes, what could be the circuit coupling constraints with the global quantities ? The H-Phi formulation here, is just an another way to compute some outputs parameters from the numerical model and compare them with those obtained previously by using a-v formulation.

Thanks in advance for the help,

Yes, I’ve already tried that and it runs well.
Now I want to frame some outputs values from the numerical model by using A-v and H-Phi formulations in magnetodynamics.

Best regards,
Geoffrey

Dear Geoffrey,

Just with the figure you attach, I do not see why you need the cohomology functions in this axisymmetric model.
Defining a circuit would be enough for imposing V and getting the currents in the conductors.
Have you tried that?

Best regards,
Ruth

Dear Getdp members,

I’m wondering if it’s possible to couple global quantities (I flowing through the conductors or V between the terminals) of the 2D axisymmetric model of an inductor (see the attached figure) with the local quantites in case of magnetodynamics H-Phi formulation (by using the cohomology basis functions). I’d like to set the voltage across the terminals and then to compute weakly the current density in the conductors.
Could you give me some advices on how to do ?

Thanks in advance,
