Applying no slip boundary condition for walls in Code Saturn

[Debashis Basu]

Hello,

How can I apply no-slip boundary conditions for wall regions in code saturne ?

I have seen this subroutine
http://code-saturne.sourcearchive.com/documentation/2.0.0.rc1-4/usclim_8f90-source.html

I want to have the velocity components u and v to be zero at the wall as boundary condition.

How to implement this in code Saturne ?

Eager to know how these no-slip zero velocity boundary conditions are implemented in code Saturne.

Kindly let me know.

Thanks and Best Regards,

I am attaching some plots of velocity to show my problem.  How come I am getting a velocity at y=0 ?

Hello,

What you get is due to the fact that velocity value is calculated at the center of the cell.

To get the profile you wish, the only solution is to make a really refined mesh at the wall.
