These #{ .. #} constructs are used for dynamic code compilation/loading,
and are typically used for boundary conditions.
Eg, tutorials/combustion/XiDyMFoam/oscillatingCylinder/ pointDisplacementy

    cylinder
    {
        type            codedFixedValue;
        value           uniform 0.00095105652;
        name            pointDisplacementy_cylinder;
        code            #{
            const scalar t = this->db().time().value();
            const scalar a = 0.001;
            const scalar f = 200;
            operator==(a*sin(constant::mathematical::twoPi*f*t));
        #};
    }

The 'value' entry has been generated by the boundary condition, and is
the only entry that ParaView needs to represent the boundary values.
The code entry can be silently skipped over with no ill-effect.
