Yes, James Parkus. This approach is definitely valid, and a common practice followed by the users.

James, You can use the FlexBody to Solid contact where the Solid is the sphere with 0 mass properties and small radius created on the interface node of the nonlinear FlexBody. Regards Prerak

Thanks for the great webinar Rishikesh! I think I've got a pretty good understanding of the use cases and limitations of MaxFlex but I do have a quick clarification to ask. Can you please re-iterate the abilities and limitations for using Nonlinear Flex Bodies in contact with another Nonlinear Flex Body or a Linear Flex Body? I understand that in it's current configuration, MaxFlex does not allow contact with a Nonlinear Flex Body and a Rigid part directly, but it could be "tricked" by attaching a rigid body (like a simple sphere) to a pre-defined interface node on the Nonlinear Flex Body then applying a contact force definition between that spherical rigid body and another rigid body.

Prerak, what about Nonlinear Flex Body contact with a Linear Flex Body (MNF)?

Okay, I understand. I was curious if I could do nonlinear flexbody contact with a linear flexbody without having to attach a rigid sphere to the nonlinear flexbody. Sounds like that's not an option though, so that's good to know. Thanks!
