 In addition, there is complexity in enforcing contact conditions and managing fluid discretization in and near the contact region. Structural contact is addressed using a node-to-segment approach based on Lagrange multipliers, with an algorithm to identify the contact occurrence point, as demonstrates as follow:

 The following simulation aims to represent the interaction between both leaflets present in the cardiac aortic valve. A time- and y-coordinate-dependent parabolic inlet velocity profile, in a laminar regime, is prescribed at the left part of the fluid flow.

 This last case is an extension of the previous problem, where the distance between the leaflets is reduced, while keeping the other distances and boundary conditions unchanged. Thus, the structures effectively come into contact, as demonstrated bellow:
