ansys 可以模拟电机转子旋转的动态吗？

如题，找了很久都找不到方法。谢谢！

可以啊，很多资料都有，怎么能找不到呢？

!  example of computing the emf in a coil for a 2D planar model.  The emf is produced
!  in a coil as a magnet moves across the face of the coil which has a 3 cm inner dimension. CEs
!  are used to join the two models at the common interface.
!
!  For 2D, the flux is the difference in Azs of the coils cross sections factored by the thickness.
!  The example assumes an average velocity of the magnet.
!
!  This example is for ONLY for the demonstration of the CEs, using Tables, and *voper commands.
!
!  left coil section:  real=2 mat=1   (1 cm x 1cm)
!  right coil section: real=3 mat=1   (1 cm x 1cm)
!  air    : mat 1
!  magnet : mat 2  (.5 cm x 1 cm)
!  interface between models is at y=0
!
!   output array:
!   emft table
!    emft(i,0) = index is X coordinate of magnet
!    emft(i,1) = flux in coil for each position of magnet
!    emft(i,2) = derivative of "1" times factor

虽然这个不是旋转，但是有移动有耦合，旋转所需要的基本元素都在这里了。解耦好像没有，不过肯定不难找。
