Dear all
I have been studying the groovyBC boundary condition these days.But I am confused in understanding something.
The following is my inputing file for pressure p.
-------------------------------------------------------------------------------------------------------

dimensions [0 2 -2 0 0 0 0];

internalField uniform 0;

boundaryField
{

SIDE
{
type groovyBC;
value uniform 0.1;
valueExpression "Pside";
variables "Pside@SIDE=p;";
}
OUT
{
type zeroGradient;
}
IN
{
type zeroGradient;
}
}
----------------------------------------------------------------------------------------------------------
Does it mean that I am using the state of the fields P on the same patches(in my case it is SIDE) from the previous time-step or iteration to evaluating the pressure expression in run-time?

According the original description from website http://openfoamwiki.net/index.php/Contrib_groovyBC
"groovyBC provides the ability to access fields from remote patches (other patches present within the current simulation). When evaluating the expression in run-time, the state of the fields on the remote patches from the previous time-step or iteration are utilised."

Have I understood it correctly?
Thank you for your suggestion!
