How to add more MPCs

I want to connect the nodes of two cylindrical components with MPCs as shown in the figure.

Of course, the red one and the gray model do not share nodes. It overlaps.


I am using HyperWorks 2022.1, is it possible to connect all nodes below the tolerance value with MPC?
I have also included the equations panel in the image in case you are interested.

Furthermore, is it possible to decide which of the duplicate nodes to choose?
I think that if I choose the same node, the MPC will not be created.

Thank you in advance.

    I don't think there is a direct way of accomplishing that in HM.

    Is it really necessary to be connected by MPCs?

    If MPCs are not mandatory, you could maybe create using connectors, pretty automatically, for rigid elements, or spring elements.

    If MPCs are mandatory, I would rather try to use connectors, create any kind of element, such as plot, or rigid, and build a script to "convert" these elements into MPCs.

    I am in the process of moving work in IDEAS to HW.


    In IDEAS I am looking for something called C-DOF, which connects two nodes by means of incidentally constrained equations.
    When I imported the model created in IDEAS into HW, it was marked as a connection by MPC.

    Of course, when I created the model in IDEAS, it showed validity.

    I wish I could find one with the same functionality...

    Thank you
