Hi everyone!

I'm working on a simulation where I have a structure connected to other parts. To reduce computational costs and time, I'm considering not meshing the main structure directly. Instead, I know the maximum deformation of the structure, which occurs symmetrically at its center, and I would like to apply this directly in the simulation settings using a remote displacement linked to the faces of the connected parts.

Is it possible to simulate the stiffness of the structure in a way that realistically transmits the force to the connected parts, as if the structure itself were fully meshed?

Has anyone tried a similar approach or could suggest the best practices for setting up such a model using remote displacement, or other tools?

Hi

One way is to mesh that missing part (where black line are shown above) with shells and use there a coarse mesh. Finally use contacts to connect the shell to the surrounding 3D solid bodies shown in the image.

 

One can perhaps also use submodelling to study the part shown above in detail (perhaps directly or after the first step is done when the shell part can be removed).
