Hello Ansys Community, i have a question about connections (especially body to ground) in Ansys Mechanical.<\/p>\n

I created a simple model with two beams, which are so placed that they have concentric drillings (see in the picture below). I added a rotational connection (body-ground) on the surface of the left drilling and a rotational connection (body-body) on the concentric drillings in the middle of the two beams where they overlap. I also added a small force of 1 N on the right surface of the right beam and limited the movement to the x-y-plane.<\/p>\n

My aim was to check the equilibrium of forces. Therefore i looked at the results of the connection samples, but the results were really weird and the equilibrium didn´t equalize.<\/p>\n

After i received those results i created another model. I didn´t change most of the settings except that i replaced the body-ground connection of the left beam to fixed support. After i checked the results the equilibrium of forces equalized.<\/p>\n

 Can anyone explain to me, how Ansys is calculating this?<\/p>\n

Thank you very much for your help!<\/p>\n
