Scaling the mesh is important as the units of the model must be in meters prior to running an analysis. If the surface or volume mesh was imported using different units then the process below should be followed.
To scale the entire mesh inside STAR-CCM+ use the Mesh > Scale Mesh... menu option:
This opens the Scale Mesh dialog with all regions selected by default. Enter the scale factor into the Scale Factor text box. This is the value that will be multiplied by each dimension to scale the model. In the example below, the scale factor would convert a model that had been constructed in inches to meters.
After you click Apply, the progress bar at the bottom of the simulation tree view indicates that the scaling is being done. When it is complete it will appear as follows:
Once the operation is complete, the summary information will be written to the Output window. This is useful to check to make sure the scale factor was applied to the appropriate regions:
All active scenes will be updated to reflect the new mesh configuration.
