relative displacement as constraints (with huge nodes number)

Recommended Posts


I attempt to go through Toplology Optimisation with relative displacement (in x, y, z) as constraints and loadcases.  SoI need to select all the nodes displacements at certain cross sections, where there is the only path transfering force to design area. I am new to optistruct and hyperview, I just noticed it is possible to select cross section and read also output every nodes' displacement in Excel. My question is, does it work in this way? and if yes, How should I input these data (should be more than hundred nodes) into Optistruct as an easy way?  

A tutorial would be so appreciated!

 

Cheers!

You can use Rigid elements. This would help to transfer loads from master node to slave nodes.Then you could define master node as design constraints for displacement.Refer below tutorial:
