    Hi Felipeds,


     


    If you want to plot Reaction Force Vs Displacement as a X-Y plot, then you have to request Radioss to write the outputs in a time history file.


     


    Please refer to the keyword /TH/NODE to request the time history outputs for nodes.


     


    From the main menu bar click on Tools > Create Cards > TH > NODE > enter a name for the group and select the node of interest > Create >edit > enter the VAR ( DEF for displacement / REACZ for reaction force in Z-direction etc ..Refer to the keyword /TH/NODE for complete list of time history variables) and then, in the engine file request the /TFILE to be written at the time frequency of interest.
