Can I apply acceleration to a CMS superelement in ANSYS 10.0? I am running a
transient analysis.

You can apply the acceleration to the CMS superlement as a load vector as demonstrated in the input below. You can also apply the acceleration to the superelement in the use pass, but this is not as accurate as applying it in the generation pass. To avoid applying the acceleration to the superelement twice use the CMACEL command to apply accelearation to a component of the non-superelement elements. /solu antype,substr seopt,plate1,2 cmsopt,fix,5,0,2000 ! 3 MODES EXTRACTED BETWEEN 0 & 2000 Hz nsel,s,loc,x,1 m,all,all acel,,,100 eqslv,sparse nsle save solve finish /out, /com, /com, *===================================== /com, * Use pass /com, *===================================== /com, /clear,nostart /filnam,use /prep7 et,1,matrix50 se,plate1 finish /solu antype,trans time,1 SFE,1,1,SELV,,1.0 solve |
