Dear CFD users,

 

Can I please request information on following plz,

 

1). The bottom link for CFD-To-Mech "Pressure Mapping" from Exchange Apps -will it be included with Release 2015 CFD ???

 

http://apps.exchange.autodesk.com/SCFD/en/Detail/Index?id=appstore.exchange.autodesk.com%3Asimcfdtos...

 

 

2). More work arounds example would be required to understand the app. and utilise it to determine its limitations.

 

Many Thanks,

Cheers,

Ajay.S

Ajay,

This is something that the development teams have been looking in to.

 

For #2 I'm not sure I'm following the comment.

 

You can use the app to map pressures from CFD to any Brick/Tet meshed Linear Static Stress model in Mechanical.

There is a video on SimTV of how to use it (here)

Can this add-in be run in a configuration where the wind tunnel is modeled in CAD, and I simultate the whole assembly, instead of using an external volume in CFD?

 

In  that case, can I just suppress the wind tunnel in FEA?  or do I need the two CAD models to match exactly?  Does it matter if the wind tunnel and part interfere or will that confuse the add-in?

 

I ask because I have tried this a few times now and it always hangs  where it says "This operation could take some time please be patient" (or rather, the add-in seems to terminate without notice, since CFD still responds).

I have been patient but there are no processes running and the add-in never finishes running.

 

Thank you.

Also - do we need to avoid geometry modifications if CFD such as remove small surfaces?
