SMS:RMA4 Model Control
The Model Control Dialog is used to define general, file, and constituents characteristics. The General tab includes options to set up the period of time the model will run, and hydrodynamic and geometry scale factors. The File tab includes the time step used from the RMA2 velocity file and the time subtracted from the RMA2 velocity file, RMA4 Output files options, and Informational Files to be produced when running the model. The Constituents tab includes diffusion coefficient for the constituent, constituent control, and mass check.
