Hello,
I have modeled riser and input guide clamps by guides with gap 5 mm preventing movement lateral movement, whereas the pipe can move freely in the vertical direction.However, I extract the force load at support in gravity case, I saw that there are force in vertical direction and I can't imagine where they are from.
I tried to understand the support results, I tried on other model that has gap 2 mm, and then I extracted the displacement results. From the results, I found that global displacement and local displacement are different. To me, they are should be the same, my understand is correct or not.
and I think the local displacement is right since the deformation of pipe as the results are equal to gap size of support.
