Is it possible to first run a modal analysis with a superelement and then expand the superelement
and run a single spectrum analysis and then look at the results from the spectrum analysis in the expanded
superelement?
Yes. Here is an example. /filn,gen /prep7 et,1,45 mp,ex,1,1e7 mp,nuxy,1,.3 mp,dens,1,.0003 block,,20,,12,,4 esize,2 vmesh,1 fini /solu antype,substr seopt,sub1,2 m,all,all solve fini save /clear /filn,use /prep7 et,1,50 se,sub1 nsel,s,loc,x,0 d,all,all nsel,all fini /solu antyp,modal modop,lanb,20 mxpand,20, solve fini /solu antype,spectrum svtype,3 sed,,,1 freq,1,1000 sv,.02,1,1 srss ! use.mcom solve fini /filn,gen resume /solu antyp,substr expass,on seexp,sub1,use numexp,all,,,yes solve fini /post1 set,list ! all 20 modes expanded /input,use,mcom prdi fini /exit,nosa |
