Define Attackpoint for Force/ Simple Question?

Recommended Posts

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.

Thanks

Hi Pranav Hari

 

Yes of cause. 

 

I found out how to see the coordinations of cog  and created a node there. This is also the attackpoint of force.  But i cannot create a connection with the center of gravity and the element of my mesh..
