Scaling the Mesh

The original mesh was not built to scale and therefore requires scaling so that the dimensions of the porous region are 0.1 x 0.1 x 0.03 meters.

Select the Mesh > Diagnostics... menu item to determine the current dimensions of the porous region

Use the Mesh Diagnostics dialog to select only the Porous region and then click OK.

The dimensions of the porous region will be displayed in the Output window as approximately -0.5 to 0.5 in the x-direction, 0.435 to 0.735 in the y-direction and -0.5 to 0.5 in the z-direction. Without any further action, these values will be interpreted by STAR-CCM+ as specified in meter units. The region therefore needs to be scaled by a factor of 0.1 so that the dimensions are correctly interpreted.

Select Mesh > Scale Mesh... from the menu bar.

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

Enter a value of 0.1 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 visualization toolbar 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 again and review the output values.
