Detailed Description

template<class Type>
class Foam::Function1Types::Function1Expression< Type >

Function1 with values supplied by a parsed expression.

Usage

Example:

\<patchName\>
{
    type            uniformFixedValue;
    uniformValue
    {
        type            expression;

        // optional variables for use within the expression
        variables
        (
            "start = 0.5"
            "stop  = 1"
        );

        // A step function
        expression
        #{
            mag(arg() > start && arg() < stop) * vector(1, 0, 0)
        #};
    }
}

Very much like '#eval' but runtime
