2.2.6. Interpolator Tab

Select the Interpolator tab. If this tab is not visible, ensure that in the Run Definition tab, Show Advanced Controls is selected.

  • Under Run Priority, you can select Idle, Low, Standard or High. For a discussion of these priorities, see The cfx5control Application in the CFX-Solver Manager User's Guide.

  • You can override the precision set on the Run Definition tab by selecting Override Default Precision and then setting the precision. For details on the precision of executables, see Double-Precision Executables.

  • You can override the problem size capability ("large problem" or not) set on the Run Definition tab by selecting Override Default Large Problem Setting and then setting the problem size capability (via the Large Problem check box). For details on the problem size capability of the executables, see Large Problem Executables.

  • If required, you can adjust the memory configuration under Interpolator Memory. For details, see Configuring Memory for the CFX-Solver in the CFX-Solver Manager User's Guide.

  • Optionally select Threading Control, then choose an Option:

    • None

      Use only one thread.

    • Number of Threads

      Set Number of Threads to the maximum number of threads that may be used by the interpolator.

    • Hardware Capacity Fraction

      Set Value to the number of threads used by the interpolator as a fraction of those available on the current hardware.

  • You can select Domain Search Control to access the Bounding Box Tolerance setting (see below).

  • You can select Interpolation Model Control to access the Enforce Strict Name Mapping for Phases (only available in CFX-Solver Manager), Particle Relocalization Tolerance (only available in CFX-Solver Manager), and Mesh Deformation Option settings (see below).

The Bounding Box Tolerance and Particle Relocalization Tolerance settings are described in Adjusting the Bounding Box Tolerance in the CFX-Solver Modeling Guide.

The Enforce Strict Name Mapping for Phases setting controls how fluids are mapped between the Initial Values files and the Solver Input File. By default, when interpolating from multiple Initial Values files onto a single Solver Input File, if each Initial Values file contains just one fluid, then the CFX-Interpolator regards all of these fluids as being the same fluid, regardless of the Fluid Definition name. You can change this default behavior by turning on the Enforce Strict Name Mapping for Phases setting. This forces the CFX-Interpolator to use the Fluid Definition names to match each fluid from each Initial Values file with the appropriate fluid in the Solver Input File.

The Mesh Deformation Option setting controls which mesh in the Initial Values File is used to check the mesh displacements: the initial mesh or the final mesh. The options are Automatic, Use Latest Mesh, and Use Initial Mesh. When the Automatic option is selected, the initial mesh will be used if the Continue History From check box is selected, and the latest mesh will be used if the Continue History From check box is cleared.
