Title	Software Description
HCS2000	HCS2000 is a transportation planning tool that replicates the methodologies defined in the Highway Capacity Manual 2000 (HCM 2000) to analyze traffic capacity and Level of Service (LOS
HEC-HMS	HEC-HMS is an application developed by the U.S. Army Corps of Engineers to simulate precipitation-runoff processes in watersheds
HEC-RAS	HEC-RAS is an application developed by the U.S. Army Corps of Engineers for modeling water flow in rivers, floodplains, and channels
HEEDS	HEEDS (Hierarchical Evolutionary Engineering Design System) is an optimization software package that allows designers to automatically and concurrently explore hundreds of design parameters and their relationships in product and process design scenarios, and intelligently seeks optimal values for parameters that affect performance and cost. HEEDS can be used to improve any engineering system (structural, thermal, fluid, electrical, etc.), including multi-disciplinary problems. In structural design applications, for example, HEEDS can evolve designs that simultaneously satisfy objectives and targets for stiffness, durability, crash-worthiness, noise and vibration, mass, cost, manufacturability, and reliability. HEEDS applies several optimization methods simultaneously, allowing each method to take advantage of the best attributes and solutions found from other parallel searches. The multiple semi-independent search processes exchange information about the solution space with each other, helping them jointly to satisfy multiple constraints and objectives. This search method is called a heterogeneous multi-agent approach. It quickly identifies design attributes with good potential and uses them to focus, improve and accelerate the search for an optimum solution.
HEEDS	HEEDS is a multidisciplinary design analysis and optimization (MDAO) software
HIPERPAV	HIPERPAV is a FHWA-developed software that predicts the early-age behavior of concrete pavements
Hyperworks	Hyperworks is a comprehensive, industry-leading simulation and computer-aided engineering (CAE) platform used to design, analyze, and optimize product performance
Hyperworks CFD Solvers	Hyperworks CFD Solvers is a comprehensive suite of computational fluid dynamics tools within the Altair HyperWorks platform designed to simulate complex fluid-structure interaction, thermal analysis, and aero-acoustics
Hyperworks Mechanical Solvers	Hyperworks Mechanical Solvers is a series of tools used to model, analyze, and optimize structural behavior, durability, and dynamics in engineering designs
