Royce,

I do.  We have been avoiding using it though because it has been very problematic for us. I can run this in 2012 overnight if you think it will make a difference.

Just checking so that if I do some test on my end I can give you a share file to try out on yours.

Can you give more detail on what you are looking for in the results?

Royce,

We are comparing pressure coefficient and velocity ratio distribution.    I have attached the published results for your reference.

Matt,

 

Here are my results from last night.  Do they look reasonable to your expectations?

Royce,

This is basically what I was seeing.  This really isn't very similar to a potential flow solution though.  There would not be low velocity regions on the airfoil surface (indicating separation), rather the flow would be attached and tangent all along the wall.  The problem is probably too basic for this software to handle.  This isn't too bad though.  It will still give us something close, I think.  Thanks for the effort!

Matt,

 

One last thing for you to checkout.  I turned on the quick forced flow solver.  When Quick Forced Convection is enabled, the flow is computed using a potential flow computation that is complete in one iteration.  When there is no heat transfer boundary conditions present, the heat transfer portion of the analysis is skipped.

Royce,

PERFECT!!!  This is exactly what I was trying to do.  Thanks!

You should be able to run a potential flow solution using the "Quick Forced" option on the "Solve-Physics" widget. You don't need to set any thermal conditions. This should give you a potential flow solution to your problem.

Matt,

 

Here is my share file.  If you could share your results on how they compare to the published results, that would be excellent!

 

Thanks,

Royce
