High Performance Software
Cobalt, widely used in a variety of both internal and external flow simulations, is a finite volume unstructured-grid Euler/Navier-Stokes solver. The fundamental algorithm of Cobalt is the finite-volume, cell-centered, first-order accurate in space and time, exact Riemann solver of Godunov. Cobalt may be run as two-dimensional, axi-symmetric and three-dimensional for arbitrary cell types.
Cobalt has the ability to restart calculations from information saved to files.
