Cobalt Solutions Announces Release of Cobalt V4.0

News Cobalt Solutions, LLC announces the release of Cobalt V4.0, the latest version of their popular unstructured flow solver.

The major new advancement in Cobalt V4.0 is an Overset module featuring an automatic grid assembly process which determines hole-cutting, overlap regions, and interpolation weights to communicate flow field information between the separate grids.

Currently, the Overset module in Cobalt V4.0 addresses the positioning of physically separate, multiple bodies. Relative positions are first established by the user at the beginning of a simulation. Over the course of the ensuing solution process, the position of any given body can be held fixed, be made to follow a user-specified path, or be allowed to change subject to the forces and moments acting on the body.

Additional enhancements in Cobalt V4.0 include the following:

  • Thermally perfect, calorically imperfect, gas equation of state
  • Blade-element rotor boundary condition, available with and without blade tracking
  • The exact Riemann solver was replaced with an in-house developed method to improve the capture of slowly moving and strong normal shocks, while retaining the advantages inherent to Riemann-based inviscid flux functions

A 60-day demo Overset license is available for users to test the new feature for their individual applications.
