Hi Indrajeet

This is a strange material¤

With some apdl you could set a do loop and redefine the temperatures for the nodes at the end of each small time step. The rsvx would be defined as the arbirary function of AZ. You can stop the solution, go into post1, use *vget to efficientlyget the AZ and set the nodal temperatures, then restart the solution.

Subject: [Xansys] [Emag] material property

Dear all,

I am asking this on behalf of one of my electrical engg colleague. The
question is:

Can I define electrical resistivity of a material as an arbitrary
function of AZ in an Emag 2D transient analysis. My model consists of
three materials and one of them is having this kind of characteristics.
I need to perform a 2D transient analysis with Plane 53 elements.

Hello Mike ,

I'll try the way you said but at present I don't have "rsvx-temperature" variation and I may not get also. Can I try writing UPF(to create this material) for this problem? Are UPFs supported for EMAG analysis?

You can certainly use UPFs in an electromagnetics analysis. But, as
Mike already pointed out, what you're proposing is rather strange. Are
you saying that there is a material that has properties that depend on a
mathematical abstraction like a scalar, vector, or edge potential?

Regards,
Dave
