I do not know of anything schedueld at this time.

Thank you for the reply.

I only ask because if i remember correctly, the current version of Falcon has a license that runs out in August.

Looks promising! It is easy to use and is focused on simulating the flow over the exterior of a vehicle without being crowded with too many tools. I don´t think one can count on it though.

• The first issue is the lack of a moving floor. Cars operate fairly close to the road and the interaction between the road surface and the undebody of the vehicle has a major effect on both downforce and drag.
• Second major issue is the lack of support for rotating bodies. Tyres can have a major effect on the flow, especially in open-wheel vehicles such as motorcycles and race cars.
• Third issue is support for exhaust flow. Since it is a highly energetic flow, the flow from the exhaust can alter the flow and be used to generate more df or reduce drag if used properly.

Are these features in the pipeline?

Thank you for your detailed feedback.

I have the same problem:

Falcon.exe
Project Falcon 2012
on
Windows XP Pro 64
SP 2

After installation, attempt to run by clicking installed icon... Get the following error
Falcon Application
Exception caught whilst running WindTunnelApp: 'pack://application:,,,/WPFOpenTK;Component/Themes​/ExpanderTemplate.xaml' value cannot be assigned to property 'Source' of object 'System.Windows,ResourceDictionary'.

Please HELP !!!

This error message indicates that your system is lacking a component that Project Falcon needs in order to run. Sometimes you can resolve this by getting newer system libraries. One of these new libraries may contain the missing functionality that Project Falcon is looking for. You should at least try Wndwos update and get all of the updates available for your system. This is not a guarantee, but it is worth a try.

where can I find lift coefficient's or lift values on this software?

Thanks

I was wondering if anybody could help me. I have modled a car on Inventor and pulled it into Project Falcon as an STL file, I have simulated it but dont have any idea how to read the results, the graph on the bottom of the screen shows me the drag coeficient (which I need) but this changes as the time on the graph changes, this is onfusing me because I thought the air flow over the car was constant meaning the drag coeficient should be constant.

Also if there is anything else i should be looking out for in these tests then please tell me.

Thank you.

You need to allow the results to converge, it will change a lot for the first 1-2 hours then starts to home in on the actual number Nick

In case anyone's around, will Falcon eventually produce a Cd in 2D (Concept) mode, or only in 3D (Simulation) mode? Asking because I'm going to be waiting for hours either way, trying to model a cowling/duct in a 2x2x2.25m control volume, with 0.01m voxels on an AMD 64 X2 5200+ (2.71GHz) and 3GB of RAM on XP Pro SP3. Running in 2D mode just now, it's ticking along at what looks something like 1fps. It would be nice to be able to use some degree of 'smart meshing', or essentially telling falcon to use less elements/'voxels' in certain parts of the control volume, such as in the gaping hole in the middle of this model. I think that's what allenhung was trying to get at earlier.
