I thought the same thing.

I was wondering what value should I be taking for the pressure and velocity? average values?My pressure values are varying from 99200+450.

Also, how do we say it is mesh independent solution? My previous mesh did not have this big oscillation. The pressure was varying from 99010+50.

So, this can be considered mesh independent solution?Also, if my next mesh refinement oscillates more, what mesh I should be taking as final?

What are the units of pressure? If in "Pa", then you have to look into youe mesh, solution. Something gone wrong.

Yes the units are in pascal. Why is it wrong?

Can someone suggest me ? :confused:

Looks too big number, whats your boundary conditions at inlet. is there any possibility to share your mesh or case files?

Boundary conditions are fine. Sen you a mail.

P.S I am monitoring pressure and velocity values at a point

what are the boundary conditions at inlet and outlet

done meshing and solution. Results seem ok and maximum velocity is 70 m/sec


1. Mesh scaled by 0.001 in all directions.

2. Pressure inlet and pressure outlet were used with given boundary conditions

3. Pressure based coupled solver.

4. 2nd order unwind for convection terms

5. pseudo transient and high order term relaxation used

6. Y+ is less than 6 and therefore qualifies for integration to wall approach along with SST turbulence model.

7. Flow is assumed to be incompressible (need confirmation)

Enjoy...

Hi Far,

Thank you so much. The results seem to be good.

1. Why did you scale the mesh?
2. I have compressible results to compare with. So I am doing compressible flow.
3.What is this "higher order relaxation" you used?
4.My target is y+<1(or ~1). Also what do you mean by " integration to wall approach" ?
5. Also, by how many lengths did you extend the domain?

I am not able to download the file. Also, can you please email me the file or link instead of uploading here and yeah can you please answer the questions I have asked earlier.
