If you have successfully run your case file and you are getting error only during display of grid,(not only for this, for all different cases too) then it is problem with your graphics card.

Please use the following commands when you launch fluent from command prompt. fluent [version] -driver x11 for unix. fluent [version] -driver msw for windows.

You may have to upgrade your graphics card driver. It should be available on the site of your graphics card vendor.
