13.2. Limitations

  • Operating point cases are not supported in Ansys Workbench.

  • Operating points are not supported in a System Coupling analysis.

  • Modifying the internally stored command language or table data in an operating point results file (mres) can lead to:

    • Unexpected results during postprocessing

    • Failure of the CFX-Solver to detect modified operating points during a restart.

  • CFD-Post cannot process an operating point case that has different meshes between any two operating points. Although operating points can have mesh changes, for example due to mesh deformation or the use of multiple configurations, CFD-Post requires that all operating points in an operating point case have corresponding mesh changes.

  • User locations that are created directly in CFX-Pre (for example, a user line with the Two Points option) cannot be changed between operating points.

  • For Transient Blade Row simulations, CFX-Pre must be able to evaluate the Transient Method "Timestep" value when the Solver Input File is written; this value cannot change between operating points. This implies that the Time Period cannot be specified using an expression that depends upon any operating point table functions.
