Hello,
I would like to simulate a void as a region within my model that should not experience any deformation - to not damage any structure that may be place there e.g. a bearing.
This is to be for a topology optimisation simulation, then how (if it is possible) can it be approached so that the optimal topology maintains the shape of the void?
To expand, if I have a circular hole where a bearing should be placed and I do not want the deformation of the model to damage this bearing, how can I contrain the hole to maintain its shape during the topology optimisation?
I would not like to use RBE2s or a nondesign space as this will effect the way the load paths are transferred.
Will RBE3s work?
If not, is there an alternative?
Thank you in advance.
