Problem in SAT file saved form Solidworks 2011

Hi All,

I saved my project as SAT file .. When I sent it to Ansys Designmodeler ,I find that the upper surface of extruded body  (800 m depth)  is divdied as shown in Fig.

I'm also tried IGES file but the same error occur

Is this error from SolidWorks 2011 or Ansys13?

Thanks in advance
