Thanks Dan. I just found reference to the .SELD file in the Help. Below is what I did to define the superelement with the SE command and then apply the load. What stumping me is that it worked the first time, but won't come in again. I only created one load vector, so I'm pretty sure it is load vector number one. /prep7 cmsel,,vRing allsel,below,volu vclear,all et,50,matrix50 type,50 se,eRing1 *get,eRing1,elem,,num,min allsel save fini /solu sfe,eRing1,1,SELV,,0.5*PreLoad Thanks, Doug Scott Inertial Sensors Products Redmond (425) 885-8267 (425) 885-8579 fax Doug.Scott2@H... -----Original Message----- Sent: Tuesday, July 10, 2001 9:11 AM To: xansys Doug, It's been awhile since I've used superelements, but my notes indicate that the load vector is stored in the {jobname}.seld file.
