Type 2 interface

Hi all.

In the User's guide I found that 'Only contact interface types 5, 7, 10 and 11 are available and are supported in RADIOSS Implicit.'

But in the Example 16 they used contact type 2 for implicit solver.

Could you please explain me?

    Hi Pohan,

    Type 2 interface is a kinematic condition and so it was not listed under contact interface,

    Type 2 is supported for RADIOSS implicit.

    Thank George.

    Could you please tell me which contact is recommended for the quasi static problem?

    Hi,

    Contacts are defined based on the application. For eg, if user is expecting an edge to edge contact Type 11 will be used.Type 2 interface is a tied interface that kinematically connects a set of slave nodes to a master surface.and thus it will not allow relative motion between the parts. If user expects a relative or sliding motion between parts Type 7 interface should be used, which is a multi-usage impact interface, modeling contact between a master surface and a group of slave nodes.
