NSMB Code 

In 1989, Navier Stokes Multi-Block (NSMB). This code has been created by european research laboratories in aerodynamicsuch as École Polytechnique Fédérale de Lausanne (EPFLausanne), KTH, CERFACS, IMFT, EADS, SAAB Military Aircraft, CFS Engineering, ETH-Zurich, IMFS de Strasbourg. Its was designed for parallel computing by solving blocks in parallel on different processors. NSMB enables to solve Navier-Stokes equations on a mesh divided in several blocks. Thanks to this approach, we can mesh the structure with a complex geometry

 

Simulation

Figure 2.1 – Problem scheme

During the first week, we worked on a 2D model SST k-omega. As a first step, we worked on a simulation where the two cylinders were immobile to study results on position cylinder and force coefficients.
