Hello all,

I just wondered if ".*" means "for all" patches in this snippet from a pointDisplacement file; kind of like in SQL where you use something like "select * from ..."?

boundaryField
{
    ".*"
    {
        type            uniformFixedValue;
        uniformValue    (0 0 0);
    }

thanks!

It is a regex (regular expression) - POSIX flavour.

What does it mean though, does it simply apply to every patch that is not otherwise defined in the same file?

Yes. You could test this by removing it -- should trigger a crash and a message to the effect of "patch not defined in pointDisplacement.boundaryField".

I see, on wikipedia it says

"s.* matches s followed by zero or more characters, for example: "s" and "saw" and "seed"."
