Cannot Plot Beam 3 Displacement Information
Cannot Plot Beam 3 Displacement Information
(OP)
Hello,
I am new to Ansys so forgive me if I am asking a stupid question. The problem I am having is that I cannot plot the UY beam deflections. The end rotations can be plotted and match exactly with theory, but for some reason the displacement data within the results does not seem to be present. I would like to graph it across the beam element, but for now I would settle with just getting some results.
My model consists of a single beam modeled with two nodes 24 inches appart. I am using the BEAM 3 element and applying to concentrated moments at both nodes (i.e. M1=-M and M2=+M).
Not sure what the deal is. Would appreciate any help anyone can offer.
Thanks,
Steve

Here is a better explination of the model. Single beam element. Node 1 is located at 0,0,0 Node 2 is located at 24,0,0. Beam element 3 is the element type. UX and UZ are constrained at both nodes 1 and 2, MZ at nodes 1 and 2 are unconstrained.
Loading consists of a negative moment applied to node 1 and a equal but positive moment applied to node 2.
After solving the problem, I plot the nodal solutions for the rotations. The values at nodes 1 and 2 are correct with theory and the plot shows the distribution of the rotation throughout the beam element from node 1 to node 2 (i.e. left to right).
However, when I try to plot the nodal solution for the vertical displacement throught the beam element (i.e. UY) Ansys does not indicate an answer or I am not aquiring the results for UY correctly.
Thanks,

What is stumping me is why I can get a nodal plot through the beam element showing the rotational displacement (about the z axis) and can't create a nodal plot of the UY disp.

Thanks a million for the insight. I see it know. I went back through the Ansys theory and looked at the shape function equation itself. I guess I had a momentary lapse of stupidity.
Thanks again for your help.
