About NS2DDV
------------
The NS2DDV Matlab toolbox is an open-source program written in Matlab for simulating 2D viscous, incompressible and inhomogeneous flows. The computation kernel of the code is based on Finite Elements - Finite Volumes hybrid methods applied on the 2D Navier-Stokes equations. For Windows, Unix and MacOS workstations equipped with a Matlab license, users can easily run the NS2DDV code by modifying a list of parameters and visualize the fluid dynamics that are simulated.
The Matlab source code has been initially developed by the team SIMPAF (SImulation et Modèles pour les PArticules et les Fluides) of INRIA Lille - Nord Europe in cooperation with the Paul Painlevé mathematics laboratory (CNRS-UMR 8524). See History section for more details.
The code is still under development under the supervision of E. Creusé (Université Polytechnique Hauts-de-France), Caterina Calgaro (Université de Lille) and Alexandre Mouton (CNRS Lille). It is the developers' aim for the software to be used by the scientific community so as to test it, evaluate it and improve it. If you want to discuss or share your works with the authors, please do not hesitate to contact them (see Team section for contacting the developers).
