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？ 回复 2# 沙隆巴斯请版主发点相关资料，谢谢！crray444@163.com 哪有啊，找不到啊，都保密！ /out,emf1,out

!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。
