FLUENT®

Requirements for the model in case the CFD solver FLUENT® is used.

  1. The CFD model must be an ANSYS® FLUENT® model. The following model components are required: ANSYS® FLUENT® case (.cas) file in binary format.
  2. Physics is limited to incompressible, isothermal, steady state flow problems.
  3. The flow problem should not be of low Reynolds number type.
  4. Extended physics like multiphase flow, moving mesh, and free surface capabilities are not permitted.
  5. The cells that make up the optimization area must be assigned to one or more fluid cell zones.
  6. There must be at least two different non-wall boundary regions, namely one that provides inflow and one that provides outflow.
  7. Symmetry boundary conditions are not generally supported.
  8. A boundary zone must not be distributed about multiple (disconnected) surface areas. Such regions must be broken down into multiple boundary zone definitions that is one boundary zone for each isolated surface area.
  9. The model might not contain any "porous jumps" in the design space that is in that region of cells that are to be used for the optimization.
