RS2N is a private research laboratory developing solutions based on numerical simulation of scientific problems, arising in the physics and mechanics of continuous media.
RS2N develops its own theoretical models and numerical methods, all embedded in a proprietary flow solver: the DALPHADT code (3D, parallel, working
on unstructured meshes,
both explicit and implicit).
