Hello, I have found it difficult to find any information on the '*' character used in OpenFoam to apply a value to variables matching the associated pattern. It is likely an easy usage, but it would be nice to have this better documented and understood.

One example that I know of is to select all keys in a dictionary one should use something like the following (which would set all relaxation factors to 0.9, not really recommended):

relaxationFactors
{
    fields
    {
        ".*" 0.9;
    }
    equations
    {
        ".*" 0.9;
    }
}

First, why is the '.' included in this case? Second, and more important, how can one select all variables of a specific pattern, such as field or equation variables which end in '...Final'?

Hello Dylan,

Have a look at the Regular Expressions section of the user guide:

It should answer your questions!
