Is there a way to get participation factors for a PSOLVE PRESTRESS modal?
Based on the test below, you can run a spectrum analysis after the modal to obtain participation factors in the x, y, and z direction. These spectrum runs are very fast. /prep7 et,1,45 mp,ex,1,1e7 mp,nuxy,1,.3 mp,dens,1,.00027 block,,20,,1,,.5 esize,.5 vmesh,1 nsel,s,loc,x,0 d,all,all nsel,all fini /solu antyp,static nsel,s,loc,x,20 f,all,fx,10 nsel,all nlgeom,on pstres,on solve fini /solut antype,modal modop,lanb,10 upcoord,1 mxpand,10 psolve,eiglanb psolve,eigexp fini /solu antyp,spectrum spopt,sprs freq,1,1000 sv,.02,1,1 svtype,3 sed,1,0,0 ! x participation factors solve *get,pfx1,mode,1,pfact ! etc... sed,0,1,0 ! y participation factors solve sed,0,0,1 ! z participation factors solve fini |
