    In RADIOSS, some of these errors are automatically solved by it removing some nodes from the interfaces.

    But essentially this is a modelling error that should be avoided.

    A kinematic condition creates a master-slave relationship between a master segment, and a slave node. Just like Rigid bodies create a master-slave relationship between the center node and its slave dependent nodes.

    Essentially when you have 1 slave node under the influence of 2 different masters.2 master segments "giving orders" to the same slave node.

    This brings a matematic conflict: which segment will the slave node follow?

    So, in general, try to avoid these conflicts, or if they're inevitable, try working with some contact parameters to handle this, such as removing nodes from interfaces.
