Abstract:
In the present work, the coupling of computational subdomains with non-conforming discretizations is addressed in the context of residual-based variational multiscale finite element methods for incompressible fluid flow. A mortar method using dual Lagrange multipliers is introduced for handling the coupling conditions at arbitrary fluid-fluid interfaces. Recently, mortar methods have been successfully applied in the field of nonlinear solid mechanics, for example, to weakly impose interface...     »
