2D Analysis in CFD

Anonymous — Wed, 22 Mar 2017 14:21:28 GMT

Hello Guys, Nice to post at this community again.

I have tried, in both Inventor and Autodesk SimStudio Tools 2016, in xy plane, and convert to igs, sat, and step file. I am still not successfull to import geometry to Autodesk CFD 2017. Please show me, step by step to simulate 2d geometry. This is the print screen:

Hi,

Might you be able to share the CAD file so we can make a quick check? It is possible you have done nothing wrong at all 🙂

Oh I forgot sorry about that. Here are my simstudio file and several
imported files.

Try again? Maybe zip it up 😉

Thanks John,
what is suitable turbulance model for water hammer?
and how can I choose time step for water hammer?

Hasan

For this I might use SST

The time step is impossible to define without experimentation though, the smaller the more stable it will be. Then at a point, reducing it further will make no difference, this is the point you need to find 🙂

John, here is my zip file.

Thank you

Hey,

What CAD are you launching from? If Inventor, do you have the native geometry?

Which file are you hoping we can look at? There are five here.

Thanks,

Jon

Maybe zip it up? Or use Dropbox/Wetransfer 🙂

This is my file in zip.

Or could you mind to send me a good one for 2d simulation (ipt and sat
file) (dimension of rectangle L=5m and W=20mm), so I can look and do the
simulation 2d.

Hasan

Try again? 🙂

I suggest you use a 3rd party option 🙂
