R. Codina, J, Principe, O. Guasch y S. Badia, Time dependent subscales in the stabilized finite element approximation of incomprensible flow problems.

In this paper we analyze a stabilized finite element approximation for the incompressible Navier–Stokes equations based on the subgrid-­‐scale concept. The essential point is that we explore the properties of the discrete formulation that results allowing the subgrid-­‐scales to depend on time. This apparently ‘‘natural’’ idea avoids several inconsistencies of previous formulations and also opens the door to generalizations. 

ICR is an Acoustic Engineering resolving problems of noise and vibrations. ICR works for the railway, car, industry, construction and environmental sectors. The company researches (R+D) new methods to solve vibroacous-tic problems. ICR also designs software for quality control and transmis-sion loss and teaches acoustics to private companies and official colleges.
