Hi everyone,
I am trying to define a different boundary condition for the salinity S if the velocity on my boundary is inflow our outflow:

• fixedValue 1 if inflow
• zeroGradient if outflow

I use the following code unsuccessfully (nothing happened):

Sea
    {
        type            groovyBC;
        valueExpression "1";
        gradientExpression "0";
        fractionExpression "(U&normal()>0)?0:1";
        value uniform   0;

    }

Thanks you
Loïc

Greetings to all!

@loic_d: From your description... have you tried using the boundary type "inletOutlet"? See the last table on this page: http://www.openfoam.org/docs/user/boundaries.php [^] - the reference to "p" is actually in reference to the field where the boundary type is defined.

Best regards,
Bruno
