Exporting Data to Abaqus

When the export action is executed, an Abaqus .inp file is produced that contains mapped data from the Simcenter STAR-CCM+ solution. This file is a standard ASCII-format keyword-driven Abaqus file.

Simcenter STAR-CCM+ automatically writes the corresponding keyword for the type of field data that is exported from the CFD model at the top of the data set:

• Pressure loads are defined via the *DLOAD keyword.
• The heat flux is defined via the *DFLUX keyword.
• Film coefficient and temperatures are defined via the *FILM keyword.
• Temperatures on surfaces are defined via the *BOUNDARY keyword for use in a heat transfer analysis.
• Temperatures on a volume are defined via the *TEMPERATURE keyword, which can only be used in an uncoupled temperature-displacement analysis. It cannot be used for heat transfer or coupled temperature-displacement analyses.

You can use the exported field data from Simcenter STAR-CCM+ in an analysis job by adding an extra line in the job file (.inp) that instructs Abaqus to read in the load data. This line uses the *INCLUDE keyword, and is added in the history section of the input file in the appropriate load step. For example, the following line would be added between the *STEP and *End Step keywords for the step in which the load data is applied to the Abaqus model:

*INCLUDE, input=mappedHTC.inp

Where mappedHTC.inp is the name of a data file containing mapped heat transfer coefficients from Simcenter STAR-CCM+.
