Hi, I am trying to model a quarter model of quadcopter drone. 

I wanted some guidance on two surface contacts, I have attached the snapshots of the two cases.

Case 1: Contact between motor and a spinner: The top part of motor rotates with the spinner, now I am confused as to what type of contact is it.

Can it be a regular glue or special glue contact or should I join it using RB2 and make the dof about vertical axis free (to keep the rotation effect on)

Case 2: Contact between quadcopter arm and plate. There is a bolt connection that I have modeled using bolt element but what about the rest surface in contact, should it be a glue contact only.

 

Thanks.

    Hi Ashwani,

    This query is much related to Nastran solver. Please get in touch with the Nastran support team.

    We can guide you if you are solving with OptiStruct, which is the structural analysis solver of Altair.
