FVS Keyword Component Files (Addfiles)

Sets of FVS keywords may be saved so you do not have to re-create them each time you start an FVS simulation. These files are called keyword component files, or "addfiles". They may be added to a simulation by simply reading them into the simulation.

Keyword component files have been created by members of our staff and others to perform complicated interactions with the FVS models. These are often created to provide actions that are not currently included in the FVS models.
