Simulation problem flux2D:
(OP)
Hello everyone.
I encountered a problem in my simulation by the software flux2D and I could not find a solution.
I made a simulation of a conductive plate which moves between two permanent elements to see the currents induced on this plate.
After the realization of the geometry, the automatic mallaige and the physical part. Thus verifying each part successfully. Even the verification of all the project also is successful.
The execution lasted after 30 seconds of calculation.
A message appears and tells me:
Not respecting a volume. Please check volume 4;
REMUSHING of Mechanical assembly Impossible at current time step.
Remushing ofMechanical assembly Impossible at the previous time step.

I can do absolutely anything. I'm an expert! https://www.youtube.com/watch?v=BKorP55Aqvg

RE: Simulation problem flux2D:
You can consult the pdf file that contains the simulation device.
If you like, you can tell me the shape of the currents induced on the plate (the plate has the shape of a parallelepiped).
There is a displacement of the plate along the y-axis of a Cartesian coordinate system. (Will the induced currents take the form of the loops in the plane perpendicular to the y-axis).
Again I attached simulation file
A big thank you MagBen

You find below the link of the PDF file which I do the work in.
RE: Simulation problem flux2D:
Let's get to the basic: The induced eddy current will against the change of magnetic field. In x-y plane, when the plate moves from left to right, the right portion of plate under the right edge of magnet will "see" magnetic field decreasing, which will induce eddy current counter clockwise (view from the top) to generate a B field with the same direction of permanent magnet. The left portion of the plate under the left edge of magnet will induce eddy current clockwise to generate a B field with the opposite direction of magnet, because this portion of plate "see" field increasing.
RE: Simulation problem flux2D:
Finally: we will see loops of currents concentrated on the y-axis.
I do not know is that this is just because I found in the PDF file that I attached the existence of the component Jy despite the motion is along the y axis?
Can you explain this? And the validity of the law of J = sig * (Vy ^ B)
I am still grateful
My deepest greetings?
RE: Simulation problem flux2D:
greetings
RE: Simulation problem flux2D:
If your conductive plate is made of copper or aluminum, not a steel or other soft magnetic material, you may ignore the B field in X- or y-axis.
RE: Simulation problem flux2D:
So that at the end we have the component of x on account of the motion along the y-axis.
The conductor is thick (its dimensions 50 * 140 * 10 mm3).
And also the skin effect was neglected because of the movement at low speed.
thank you again
