Hey guys,

I was trying to set up a force-displacement graph in ansys apdl, so a created a few load steps, but it doesnt quite seem to work. Here is the part of the code.


/solu
autots,on
nsubst,5,5,5
outres,all,all

solve
fini

/POST26
NSOL,3,45,U,Z
RFORCE,4,45,F,Z
/AXLAB,Y,FORCE
/AXLAB,X,DISPLACEMENT
XVAR,3
PLVAR,4

This plots a graph, but nothing shows up on it.

When i look into the timehist post proc menu, the deflection variable shows up fine, and lists the deflection for the 5 time steps, but the force shows up as invalid and im not sure why.

Also if i understand right, it will only show the reaction force of that node right? So how do I change that to include the force across the whole cross section?

Any help would be appreciated!

Thnaks!
