Start up STAR-CCM+ in a manner that is appropriate to your working environment and select the New Simulation option from the menu bar.
Continue by importing the mesh and naming the simulation. A hexahedral cell mesh has been prepared for this analysis and is stored in a .ccm format file.
doc/tutorials/multiComponent subdirectory of your STAR-CCM+ installation directory and select file dilPipe.ccm.
STAR-CCM+ will provide feedback on the import process, which will take a few seconds, in the Output window. A scene displaying the imported mesh will be created in the Graphics window.

Finally, save the new simulation to disk under file name dilPipeSteady.sim.
