Validation and comparison with other CFD-software

Participants : Daniela Capatina, Didier Graebling, Julie Joie, Eric Schall.

We intend to compare computations based on Concha   with other codes at hand of the prototypical test problems described above. This allows us to evaluate the potential of our numerical schemes concerning accuracy, computing time and other practical expects such as integration with mesh generators and post-processing. At the same time, this, unfortunately very time-consuming, benchmarking activity allows us to validate our own library. The following commercial and research tools might be considered: Aéro3d (INRIA-Smash), AVBP (CERFACS), ELSA (ONERA), Fluent (ANSYS), and OpenFOAM (OpenCfd), and Polyflow^® (ANSYS). So far, we have compared our code for the Giesekus model of polymer flows with the commercial software Polyflow^®, see Section  4.2 .
