Hi <\/p>\n

I have modeled pipes and elbow (picture below) using *ELEMENT_BEAM_ELBOW using LSDyna. My model converged but somehow the results are not making sense. The von misses stresses are way larger than what is expected. When I check the d3plot, I found that the elbow elements are separating badly (picture below). It happens for the second elbow as well. My *ELEMENT_BEAM_ELBOW  definition is as below:<\/p>\n

*ELEMENT_BEAM_ELBOW
       1       1       1       4       3 (element ID       PID          N1     N2     N5          and the row below is midpoint N3)
       2
       2       1       4       8       3
       6<\/p>\n

………………………………………<\/p>\n

*INTEGRATION_BEAM
         1         0       0.0         9         2
  0.161925  0.159125       0.0       0.0       0.0       0.0       0.0       0.0<\/p>\n

*SECTION_BEAM
         1        14       1.0        -1         2       0.0       0.0         0
       0.0       0.0       0.0<\/p>\n

<\/p>\n

 <\/p>\n

<\/p>\n

 <\/p>\n

Could anyone help me in this regard by giving me some suggestions what I am doing wrong? I did not get much help from manual and online. Thanks again.<\/p>\n","protected":false},"template":"","class_list":["post-317878","topic","type-topic","status-closed","hentry","topic-tag-elbow","topic-tag-lsdyna","topic-tag-pipes-1"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
