warning in postprocessing FLU2D

lijo

I have this warning when I plot the current density in the conductors region, That's mean? How to do it well ???

"Field IsovalueSpatialGroup.regionInternalExternal must be filled.
Field IsovalueSpatialGroup.internalComputation must be filled.
Field IsovalueSpatialGroup.regionType must be filled."

e=mc^2

Are the termainals of your conductors region setted ?

positive or nagnative?

Is Flux2D and solid conductor regions with positive orientation for the current and the circuit is:

Other question (the model is 2D-AXI-SYMM of a simple 1-phase transformer):

Why the Joule Losses in the primary descrease with the frequency ?



                PRIMARY-COIL (DC-60Hz)



                SECONDARY-FOIL (DC-60Hz)

Sorry， your application is FLUX2D.........

In “Field Isovalue map" ,the current density value of whole conduction is positive, it can not tell the current‘s direction

so, maybe this is why it warned










For Aq2：
with the frequency increases, the Excitation reactance(xm) increases，so the current of primary decreases, and joule losses also decreases

With the frequency increases, the xm(magnetic reactance) increases, so the current of primary decreases, then Juole loss decreases
