Description
Summary:The purpose of this Technical Note is to describe a process of modeling flow in hydraulic structures. In particular, application is made with the unstructured flow solver, ADH (ADaptive Hydraulics model). ADH also contains solvers for groundwater and two-dimensional shallow water flows. It is capable of refining or coarsening the grid based on error estimates during flow calculations. Three demonstration applications are presented: (a) CAD-to-Grid Process Demonstration at an Intake, (b) Scalability Demonstration with Outlet Manifold, and (c) Free-surface Capability Demonstration with Supercritical Flow Contraction.
