L-shaped beam

      Hello all,

      I have a problem modeling a L-shaped beam. In APDL I simply create 3 keypoints and I join them with two lines. Then, I mesh with beam188 elements with a rectangular cross-section. I attach some images to figure out better.

      When I Activate the /ESCHAPE command I discover that there is overlapping at the corner. Actually, I do not know if it is only a graphical representation or if this overlapping could give me a problem in the results. I say this because the beam is only a part of my model, which gives me not accurate results.


      Thank you for your help.

      Kindest,


      Francesca

      HinIt is graphical representation. What APDL solving is actually line element. It appears from the image the beam is considerable thick compared to its length. That may be reason behind inaccuracy. For beam modelling, they should have higher slenderness ratio.n

      Dear,n@rkumbhar, thank you for the support! Can I improve my analysis using beam189 or should I accept this inaccuracy?n

      this requirement of slenderness ratio applies to both beam 188 and beam189 elements.n
