To verify that the initial conditions applied to the regions are correct, STAR-CCM+ allows you to perform just solver initialization to start with and then view the results using an appropriate scene.
As the colors show, the solid fin is at 343 K while the surrounding air is at 293 K. The velocity value for each cell is 0. The simulation can now be run.
If this is not displayed, use the Solution > Run menu item. You may also activate the Solution toolbar by selecting Tools > Toolbars > Solution and then clicking the toolbar button.
The Residuals display will be created automatically and will show the solver's progress. If necessary, click on the Residuals tab to bring the Residuals plot into view. The tabs at the top of the Graphics window make it possible to select any one of the active displays for viewing.
During the run, it is possible to stop the process by clicking on the 
(Stop) button in the toolbar. If you do halt the simulation, it can be continued again later by clicking on the 
(Run) button. If left alone, the simulation will continue until 1000 iterations are complete.
The Residuals display at the end of the calculation should look like this.
(Initialize Solution) button in the toolbar or use the Solution > Initialize Solution menu item.
