Solidworks makes it very easy to CAD and then validate the designs within SolidWorks environment using it built-in CFD and CAD modules. This tutorial shows how to setup a basic CFD analysis and then use its results in FEA to determine its effects on the model!
Part used here: Plate for SolidWorks: Combined CAD + CFD + FEA Tutorial
Full tutorial for GrabCAD (photos) coming soon.
Same method was used to solve this: Display Hoarding (CAD, CFD, FEA using SolidWorks)
Very easy to follow, ask questions if you are stuck.
