How to impose different inlet conditions

Post by noamc »

Hello, I am new on this forum. I am student in the mathematical field and I work in a company using Code_Saturne.
As a training, I would like to model a rejection of a chimney near a mountain (The puy de dome, France).
For now, I only use gui interface.
I made a simulation imposing a velocity of my chimney (normal to the inlet) and of my atmosphere (dy = 1.0, dx=dz=0.0) and it worked.
But now I would like to try to use an extern meteo file and I have a problem when I use for the atmosphere (basically a cylinder with an altitude of 2000 meters) "Meteorological profile from data" and "automatic inlet/outlet nature..." and for the chimney the velocity normal to the inlet.
This is the listing file :

Remark : it works when the chimney has the same B.C. than the atmosphere ( "Meteorological profile from data" and "automatic inlet/outlet nature...") but it is not exactly the simulation I would like to make.
Thank you for your time !

Re: How to impose different inlet conditions

Post by Yvan Fournier »

Hello,

Could you post the matching xml file ? And either a mesh (if nt too large) or a view of the case ?

Did you visualize the ERROR.* postprocesing file to see which faces cause issues ?

Regards,

Yvan

Re: How to impose different inlet conditions

Post by noamc »

Hello. Thank you for your answer.

Yes I visualized the faces causing the problem, they are the faces of my inlet (the superior part of my chminey).
I enclose the xml file and a view from paraview, the faces causing the problem are the blue ones.
Sorry my mesh is too important to be sent.

Best regards,
Noam
