Hi,
we would like to access one Foam::scalar that we calculate in a modified forces library to set a boundary. The library we created calculates the surface elevation depending on gamma and a predefinded direction and is called from the controlDict similar to the forces library and can be called several times with different names.
Now we would like to use these values in a wave generating boundary, preferably by specifying the same identifier in the boundary condition as in the controlDict. If the forces lib would be a registry object this would be easy, but it seems to me that only fields and some special types (i.e. Time) can be attached to the registry.
Is there any type that can hold a single value/scalar and that can be attached to the registry or can the forces object be linked to the reg., or is there a different way to pass small data among libraries?
Thanks, Lukas
