Importing STAR-CD Data

Simcenter STAR-CCM+ allows you to import mesh and solution data from STAR-CD, in order to post-process the STAR-CD solution data using the Simcenter STAR-CCM+ visualization tools. This import option does not support Lagrangian solution data.

Since the STAR-CD v4.04 release, the solution data provided by STAR (the solver) has been stored in two files: the .ccmp file for standard (restart) solution data, and the .ccmt file for transient solution data. Both of these files contain a link to the corresponding .ccmg file for the mesh data; if this .ccmg file is missing, it is not possible for Simcenter STAR-CCM+ to read either the .ccmp or the .ccmt file. This import option does not support solution data from moving mesh calculations.

The procedure for importing both mesh and solution data from STAR-CD is described as follows (assuming that the necessary STAR-CD files have been copied into the working directory):

  1. Launch Simcenter STAR-CCM+ and start a new simulation in the manner appropriate to your environment.
  2. Select File > Import > Import Volume Mesh...
  3. In the Open dialog, select the desired .ccmp or .ccmt file. Make sure that the corresponding .ccmg file is also available.


  4. Click Open.
If solution data is successfully read from the file, information on the process is displayed in the Output window. This information includes details of the solution data found in the file, and details of the scalar fields in Simcenter STAR-CCM+ to which the solution has been mapped. An example of this output is shown below.

Processing mesh: 
Mapping imported data DENS to Density
Mapping imported data ED to Turbulent Dissipation Rate
Mapping imported data H to Enthalpy 
Mapping imported data P to Pressure 
Mapping imported data SU to Velocity-X 
Mapping imported data SV to Velocity-Y 
Mapping imported data SW to Velocity-Z 
Mapping imported data T to Temperature 
Mapping imported data TE to Turbulent Kinetic Energy 
Mapping imported data VIS to Turbulent Viscosity

It is observed that solution data is read for both cells and faces during the import process. This corresponds to cell and wall data in STAR-CD.
