  3. How can I obtain an XY plot of the reaction force versus time in POST26? I need to extract the reaction force FX of some nodes fixed using D,node#,UX in an LS-DYNA model. I tried RFORCE command in POST26 but the generated variable was shown to be “invalid”. How can I obtain an XY plot of the reaction force versus time in POST26?

      Before solving, you need: EDOUT,RCFORC Then, in POST26, do, for example, the following: FILE,,HIS EDREAD,2,SPCFORC,25 This will read node 25 x, y, and z reaction forces into POST26 variables 2, 3, and 4, respectively. Plot the reaction forces versus time using PLVAR,2,3,4.
