Scaling the Mesh

The original grid was built using centimeters as a length unit, but no scaling factor was applied when the grid was saved to the .ccm file. The current dimensions of the mesh regions are already available from the mesh import process and are displayed in the Output window.

As can be seen from the output produced at import, the mesh regions extend from 0 to 10.0 in the x-direction, 0 to 10.0 in the y-direction and 0.0 to 1.0 in the (now defunct) z-direction. Without any further action, these values would be interpreted by STAR-CCM+ as specified in meters. Therefore, the region needs to be scaled by a factor of 0.01 so that the dimensions are correctly specified.

To do this, select Mesh > Scale Mesh... from the menu bar.

In the Scale Mesh dialog, make sure that the Fluid and Solid regions are in the Selected list box.

Enter a value of 0.01 for the scale factor.

Click Apply to scale the domain and then click Close.

When the Apply button is clicked, the mesh region will be reduced in size.

Click on the

(Reset) button in the toolbar, ensuring no boundaries are selected, to restore the previous viewing distance for the scaled domain in the display.

To verify that scaling has in fact been applied, you may perform the mesh diagnostics check and review the output values.
