surface load visualization
surface load visualization
(OP)
Dear all,
in the step 1 of an analysis I apply just the gravity load on a structure.
Then, in the step 2 I apply a distributed load on beams with the SFBEAM command. The value is, let's say, 10.
In the step 3, I bring this value with SFCUM and SFBEAM to 20.
In the postprocessing with /PSF, I can only visualize the load with the value of 20 which remain fixed even in the steps 1 and 2.
On the contrary, if I use the element table, all the values are ok, but I can display only the contour plot and not the vector.
Can you help me?

RE: surface load visualization
Try this:
ESEL !select elements of interest
NSLE
/PSF,PRES,NORM,2,0,1 !plot pressure normal...change Comp entry if something different is required for display
/PBC,ALL,,1
/REP
Surface forces are only plotted at where they are applied. So if you're beam is comprised only of a single element (ie. 2 nodes) you will only see arrows at the extreme ends of the beam.
Hope this helps,

But in this way I can visualize only the pressure defined in the last step of the analysis !!!

RE: surface load visualization
there may be a problem with your use of SET or LCASE (see help file in 5.4.3.1, "Notes"). Can you add some info about how you shift from one loadstep result to another?

RE: surface load visualization
with the GUI, general postprocessor->read results or simply with the command SET, NEXT or SET, PREVIOUS.
In both the cases it does not work.
