Hi zaynah,

You can set the velocity boundary condition in 0/U dictionary using fixedValue boundary condition:

inlet
{
type fixedValue;
value 4.0;
}

.. (set other boundaries similarly)

Did you take the time to read the User Guide? It would be a good start...

Have a good look at the tutorials that come with the OF installation. Having a look at examples is often more explanatory than the manual.

Just a small detail, if you add 'uniform' to the value- on field in fixedValue if you don't want to get a warning:

Quote:
inlet
{
type fixedValue;
value uniform 4.0;
}

just a remark you should enter U in vector form,

value uniform (4 0 0);

but you can put the pressure in scalar form,

value uniform 4;

good luck.
