 | |
| problems in the field of Computational Fluid Dynamics (CFD).  It is written in
 | |
| C++.  Governing equations such as the Navier-Stokes equations can be solved in
 | |
| integral form.  Physical processes such as phase change, droplet transport and
 | |
| chemical reaction can be modelled.  Numerical methods are included to deal with
 | |
| sharp gradients, such as those encountered in flows with shock waves and flows
 | |
| with gas/liquid interfaces.  Large problems may be split into smaller, connected
 | |
| problems for efficient solution on parallel systems.")
