Why do I get 'File does not exist' error in Object Module?

Q: When running the Object module it yields the following error:

     File does not exist:

     X:\WindSim Projects\[projct name]\[layout name]\object\object_4_1_a6.geo

     Error no.: 1110

     EXIT......

A: This error usually occurs when the .ows file specifies a visualization file that does not exist. To resolved the problem, open the .ows file and look for the column under "visualisation". The default file name should be "turbine_80". Make sure this file name has not been altered.
