  Dear colleagues,
  
  I'm simulating a structure where several components are connected (represented by concentrated mass, forces...). I would like to impose to the model the correct location of the CoG that came from my 3D model. Is it possible to do it?
  
  Thank you in advance.
  
  Regards.

  One method is to add a Point Mass to each component in the assembly. The point mass can be moved around until the CG of the component including the point mass is correct. Assemble all the components into a system and the assembly as a whole will have the correct CG.

  Dear Peter,
  
  I thought that as possible solution, but since I have several components, to include the mass of each one would take too long.
  
  I was searching for some direct way to force the CoG position.
  
  In any case, thank you for your reply.

  Several components sounds entirely feasible to do each one, but if you want to shorten the process, group components into subsystems and do the CG at a higher level.
