Resumen:
In dynamic mesh simulations or problems with complex geometries, it is useful to dividethe domain into several parts to mesh them separately. As a result, mesh interfaces appear for each pairof subdomains that are interconnected. In this sense, subdomains must be coupled by an interpolationtechnique or by a remeshing procedure to solve the numerical problem. The interfaces may be non-conformal, and then, connectivity information is required. In parallel computing, communication mustbe performed if the interfaces are distributed over different processors. In the present work, the imple-mentation of a parallelised strategy for a new interface technique, which is called pseudo-supermesh, isdescribed. In the pseudo-supermesh strategy, a remeshing step is achieved which invalidates the originalconnectivity between the interfaces. As a consequence, the initial connectivity must be translated into thenew mesh state where the interfaces may have a new topology. The present implementation is conceivedto handle arbitrary decompose strategies. This feature is a significant advantage in the simulation of dy-namic mesh problems, in particular for the simulation of rotating devices. A scalability test is performedusing the proposed implementation with different decomposition methods. Finally, the robustness of thecomputational implementation is evaluated with industrial problems.
