Hallo, I made 2000 iteration

Hallo,
I made 2000 iteration with HRV's settings, starting from the previous solution. Now the flow field is realistic, completely different from what I had obteined with the other settings.
But...

It's a grid I made some time ago because at the moment I don't have a good software. Howerver the geometry is very simple.

Tonight I'm iterating with HRV's settings, tomorrow I'll check if the...

BastiL,
I use a tetrahedral mesh of 1.3mil cells and I think it's quite good. Max cell skewness is less than 0.40 . However on monday I'll post the checkMesh result.

I'm sorry, Vincent RIVOLA used these settings.

On manday I'll test with the schemes you suggest. According your opinion, are the solvers OK? Is it possible make iterations faster?

BastiL,
my residuals are very low (10^-8), but the wake has an absurd shape.

The solver settings I used are:

BastiL, I have read this week

BastiL,
I have read this week the topic about Mesh3D, it's open-source and looks interesting. But I hadn't time to test it so far.
In this days I'm working with a mesh I alredy had an I'm...

Thanks, that website is very interesting, but I didn't find what I need because there are pressure data and velocity fields, but nothing about lift and drag. Instead these are the parameters I need...
