    modeling of a moving 3D magnet!

    Hi DimiZ, I solved the issue by comparing GUI method with command method, try checking your "real constants" settings in GUI, find out the undefined real constant and define it. For your command method, you need to always add "r,1" for your material 1, same as "r,N" for your material N. Hope...

    modeling of a moving 3D magnet!

    Hi electricpete, Thanks for your suggestion. I finally figure this problem out by myself. =) Andrew

    modeling of a moving 3D magnet!

    Hi everyone, I am modeling a 3D magnet and a solenoid. The magnet is moving at a speed (constant or not), and it is moving towards to the solenoid, which is static (fixed to the ground). I want to model the emf and induced current on the solenoid, due to the change of magnetic flux density...

    Model induced currents due to change of magnetic flux density

    I write the ANSYS codes for this problem today, but keep getting error message: "circuit modeling with velocity modeling effects are not available". Anybody has any idea what the problem is? I attached my codes below: ************************************** /TITLE,2D magnet-coil transient...

    Model induced currents due to change of magnetic flux density

    Hi, I am currently trying to model: a bar permanent magnet moving toward a coil, where induced current will be created on the coil due to the change of magnetic flux density. Is it possible to do this in ANSYS? or Ansoft Workbench? (with transient of harmonic analysis) Thanks!!!

    Interpolating vector data in Matlab

    Hi, Suppose there are three parameters x,y,z, where z is a function of x,y such as z=f(x,y). If I know the value of z at a specific (x,y), for instance f(1,2)=11, f(2,3)=12, f(3,4)=13, f(4,5)=14, is there a way to get z value wrt different (x,y) via interpolation? (in my case x,y,z are...

    Export results from ANSYS into other files!

    Hi, I am modeling a 2D Magnet in ANSYS and I want to export the results of the magnetic flux intensity around the magnet to some .txt or .xl file, so that I can use them in Matlab for further analysis. I tried to export the ANSYS results into some array but keep getting warning "Requested data...
