CFD 2014 Lift Simulation 2D think Aerofile Geometry

[ehtesham.bokhari]

Hello,

I am trying to setup a simulation of 2D thin Aerofile Geometry with different angle of attack.

But the issue I am facing is how to make its geometry in CFD 2014

I am familiar with Invetor.

Please guide me how to solve it.

I would be thankful if any one can give me a CDF 2014 file with 2D Geometry where I can change it.

Thanks

A very basic 2D geometry set is included with the installation.

Refer to this path: C:\ProgramData\Autodesk\Simulation CFD 2014\Tutorials\Inventor\bullet

Tutorial model to go with geometry: http://help.autodesk.com/view/SCDSE/2014/ENU/?guid=GUID-17530C86-1491-4C26-B509-81E55786DC12

Some basic rules when modeling 2D for CFD

1. All geometry needs to be on the XY Plane
2. Build the geometry in the 1st quadrant (+X +Y)
3. In inventor you will create sketches and then patch those sketches to create multipe surfaces.
4. The 2D analysis is considered a Units depth of whatever unit system your geometry is setup with in CFD.  If it is in meters than it is 1 meter thick.

thank You for guiding me.

I made a 2D geometry in 1st quadran in Inventor 2014, the     .ipt file

 and then I have three options 

1.Launch Active Model

2.Launch iParts/iAssemblies

3.CAD Entity Group

I tried two of these and it gave me error saying Aspect the CAD geometry for Problematic features.

Please guide me what am I missing 

Thank You

Hi Ehtesham,

Your best bet is to use the first option 'Launch Active Model'.

It sounds like there is an issue with your geometry - would you care to share the ipt here?

Are there any overlapping surfaces or infintely small angles?

Kind regards,

Jon

[ehtesham.bokhari]

yes, I will try that. let me do that

Hello, I have a similar problem, I have a wing modeled in Unigraphics NX and I want to do the simulation of the wing in wind tunnel for so drag and stall providing this wing, preferably want to do it in 3D, but would also be me very useful in 2D.

My file has extention .prt Thanks.

can I have you skype ID or facebook ?
