Error in Boolean operation
 

Hi everyone,

I am using Ansys 15 and trying to do CFD analysis of flow over a variable cant angle winglet. I have drawn the geometry using Solidworks 2015 and imported it as .igs format into ansys design modeler.

Now when I attempt to do a Boolean to subtract the geometryfrom the rectangular domain I get the error 'Bolean operation failed, Context: Geometry Engine, while generating Feature Boolean'.

Now can anyone help me to solve this? I have also tried body operation>cut material. it didn't work.https://drive.google.com/file/d/0B5T...ew?usp=sharinghttps://drive.google.com/file/d/0B5T...ew?usp=sharing

if you imported surfaces, designmodeler will generate that error. make sure you only have bodies
