Hello everyone, i do a FEM Project with HyperMesh and now im at a point where i need some help :/ (First time with HyperMesh) I have to do a FEM analysis where various forces attack a beam. The Problem is that the Beam is not symmetrical but i have to define a Force in direction to the Z-axis. (Picture 2) The Force should attack at the center of gravity otherwise the beam will be twisted. My Question is: Where/ how can i define that point (cog) or force where the beam only bends down and dont twist? previous attempts: Pic 3. --> But it twisted. It is logical because of the lever arm Singe Force on the Top of the beam near the CoG but also twisted My Solver is Optistruct. Pic1. Maybe someone can help me Thanks Pic.2 (Force F has to been define ) Pic 3
