Problems with geometry

I have been trying to run an airfoil. The runtimes were high so I have tried to run 2D CFD's. I cannot get any Inventor sketch accepted by Simulation 360 CFD Trial. Even a simple rectangle produces the screenshot I have attached. I am assuming you make a sketch in Inventor and then launch the CFD program to start a 2D CFD analysis. Am I wrong in that assumption?

 

I haven't found much in the help files for 2D anything. That is frustrating.

 

Is there a rule of thumb figure on how much faster a 2D analysis is versus a 3D analysis?

Hi,

 

I am guessing that you drew the sketch and then launched Sim CFD from the Inventor plug-in without generating the 2D surface itself. If that's the case, you will need to generate the 2D surface in inventor using 3D Model>Surface>Patch tool, only then should you launch Sim CFD.
