remote point in optistruct

Recommended Posts



I am doing suspension analysis in hypermesh and Optistruct solver . I have not used shaft during analysis. So, I want to use remote point at specified location and apply force at contact of tyre and road. I want to connect this remote point to tyre centre using RBE2 link. This tyre centre is also connected to bottom nodes of leaf spring.


My doubt is how to set centre of gravity for this RBE3 link at tyre centre ?  (Just like we use ICOG=3 in case of Radioss). This node of tyre centre should be fixed position.

I am not sure.. I should use RBE3 or RBE2 element for this ? Suggest me.

Hi @pratik gadve


Can you check RBODY in OptiStrut?


You can set CoG and Inertia on RBODY

Ok. Here reference node is nothing but master node on which we apply COG... Right ?


Does Rigid Body link act like Rbe3 here ? I doubt because length from centre of tyre to bottom nodes of leaf spring is different.
