When loading an existing model, EFDC_Explorer identifies the type of model and automatically sets the options on this tab, based on the data in the EFDC.INP file. In addition, the user can switch from one type of model to the other using the model selection option in the Model Selection frame. When changing from one model type to the other, the user should check the model layering and boundary conditions to ensure the inputs are correct. See Section 5.8 for the settings on the GVC.
The Global Transport Options sub-frame allows the user to select from Upwind Difference, Central Difference and Experimental Upwind, as well as to use Anti-Diffusion or Anti-Diffusion Correction methods. This option sets the same mass transport computational approach for all constituents. More granular control is available using the Details.
