Specific CAE Properties

Data mappers are created manually or by invoking a map-action on surfaces or volumes of imported models. The map-action dialog has special properties depending on the type of surfaces and the data type chosen for mapping.

Heat Transfer Export Options Reference

In coupling with CAE packages for Conjugate Heat Transfer applications, the CAE model is imported into the Simcenter STAR-CCM+ simulation. Typically, the Local Heat Transfer Coefficient (HTC) is mapped from the Simcenter STAR-CCM+ fluid boundary to the corresponding solid surface from the imported CAE model. As a fluid temperature is required to calculate the heat flux, the Local Heat Transfer Reference Temperature is mapped and exported along with HTC as well. The map-action dialog also allows you to specify a constant bulk temperature as the reference temperature. The dialog also allows you to choose the cell-center temperature in case radiation is being solved in both the solid and the fluid. The surface data mapper displays a Heat Transfer Export Options subnode when appropriate.
The Heat Transfer Export Options node is displayed if you choose all of the following:
  • Simcenter STAR-CCM+ boundaries as a source surfaces
  • Imported Surfaces as target surfaces
  • The source and target stencils set at Face
  • Local Heat Transfer Coefficient included among the Scalar Functions for mapping.

The HTC export options can be specified by selecting the node in the object tree and working with the properties.

You cannot activate both the Use Near Wall Cell Temperature and Use Specified Bulk Temperature options at the same time. However, if neither one is activated, the field function for Local Heat Transfer Reference Temperature is automatically appended to the list of scalar functions for mapping.

表 1. Properties
Use Near Wall Cell Temperature Accounts for the inclusion of radiation in the simulation. When activated, Simcenter STAR-CCM+ exports cell center temperature as the reference temperature. This is applicable in case radiation is being solved in both the Simcenter STAR-CCM+ and CAE packages.
Use Specified Bulk Temperature Controls the export of the bulk temperature. When activated, Simcenter STAR-CCM+ exports a constant bulk temperature as the reference temperature.
Bulk Temperature Specifies a value for bulk temperature.
