Product Features
Grid
Generation
 | Global Cartesian and cylindrical
co-ordinate systems. |
| Definition of local Cartesian and
cylindrical co-ordinate systems. |
| Manual or automatic creation of
vertices, cells and boundary cells. |
| Choose from hexahedral or prism cells. |
| Body-fitted, non-orthogonal
unstructured meshes. |
| One-, two-, and three-dimensional
interpolation routines for grid points. |
| Cubic splines. |
| Unstructured local mesh refinement and
embedding to locally enhance the accuracy of solutions. |
| Arbitrary mesh coupling:
Couple any two meshes by simply projecting one surface onto the
other. |
| Importation of CAD data |
Fluid
Flow Types
| Incompressible to highly compressible
transonic flow. |
| Laminar and turbulent flows. In the
turbulent case a high Reynolds k-e,
model is employed. |
| Steady and unsteady flow. Modified
versions of the SIMPLE and PISO algorithms are used for steady and
unsteady solutions. |
| Heat transfer. Convection and
conduction heat transfer; also combined fluid-solid heat transfer. |
| Multiple fluid streams. |
| Mass transfer. Mixtures of gases or
liquids containing different individual chemical species. |
| Thermal buoyancy. Other types of body
forces may be incorporated through user coding. |
| Porous medium flow. Volume and planar
resistance modeling are provided for handling flow through heat
exchangers or packed bed reactors. |
| Dispersed multi-phase flow model. A
general framework is provided for handling different combinations of
gas-solid, gas-droplet, and fluid-bubble dispersed phase situations. |
| User-defined options for programming
fluid properties such as density, viscosity, specific heat, etc. |
| Two-fluid with free surface capability |
Boundary
Conditions
| Inlet boundaries for mass, energy,
turbulence and chemical species. |
| Pressure boundaries |
| Stagnation boundaries for total
pressure and total temperature. |
| Supersonic inlet boundaries. |
| Zero gradient outlet conditions. |
| Symmetry planes. |
| Periodic/cyclic boundary conditions. |
| Wall boundaries with fixed, flux or
adiabatic conditions for temperature and chemical species. |
| Baffle boundaries with fixed, flux or
adiabatic conditions for temperature and chemical species; also
specification of fluid flow and heat transfer resistance coefficients. |
Moving Meshes
| Flo++ utilizes its arbitrary mesh
coupling capabilities to enable arbitrary sliding meshes. |
| Dynamic cell addition/removal |
Visualization
The visualization facility of Flo++ is a
powerful tool for viewing, inspecting the integrity of the mesh and aiding
in the analyses of flow results. During post processing the geometry can
be coloured with scalar values of the flow variables.
The user can interact with the geometry
displayed using the render window interactor. Interaction includes
rotation, scaling, panning, spin, and vertex picking. Interaction with the
window takes place through mouse and keyboard operations.
Different plot types can be used to
represent your geometry the best way possible. The following options are
available in forming combinations to get the desired plot characterstics:
