Why do I have to convert my mesh to an unstructured mesh?
 

Hello Guys,

I am new to ICEM, and just started doing ANSYS 14.0 ICEM tutorials. Before exporting mesh file to FLUENT the tutorial converts the mesh format to unstructured mesh !!

Why do I have to convert the mesh to an unstructured mesh format every time before solving, although I am solving a simple 2D or 3D problems with Hexahedral mesh ??

Thanks

coz Fluent is an unstructured solver.
