Why can I not calculate JXB in a SOLID117 conductor in ANSYS 9.0
as I did in 8.1?

Magnetic force calculation was made more accurate and easier to do in ANSYS 9.0 through the use of the new EMFT command. No flags need to be set before solution. Force are computed in POST1 when this command is issued based on the selected nodes. All elements should be selected. Here is a simple test of the new EMFT command used to calculate the forces between two solid117 conductors with keyopt(1)=6. It gives reasonable JXB forces. /prep7 et,1,117 mp,murx,1,1 et,2,117,6 mp,murx,2,1 mp,rsvx,2,1e-6 block,1,2,1,2,,10 block,3,4,1,2,,10 block,0,5,0,3,,10 vovlap,all numcmp,volu esize,1 type,2 mat,2 vmesh,1,2 type,1 mat,1 esha,1 vmesh,3 nsel,s,ext d,all,az,0 nsel,all fini /solu vsel,s,,,1,2,,1 nsel,r,loc,z,0 d,all,volt,0 vsel,s,,,1,2,,1 nsel,r,loc,z,10 d,all,volt,1 alls fini /solu solve fini /post1 set,last vsel,s,,,1,,,1 ! to get nodes of first conductor esel,all ! all elements should be selected emft |
