NOTE: * indicates that additional models for human simulation, such as EDHIS and GATB are not listed in this comparison.
NOTE: 2-D** indicates that EDCRASH, EDSMAC, EDSMAC4, EDSVS and EDVTS have been extended and revalidated for use in the HVE simulation environment to account for 3-D terrain, but they are still essentially 2-dimensional physics simulation programs. If you use EDCRASH, EDSMAC, EDSMAC4, EDSVS, EDVTS or EDGEN in HVE, the Human, Vehicle and Environment Editors will have additional features that are not available in HVE-2D. While some dialogs will look different between HVE and HVE-2D, the required inputs for these programs are found in both simulation environments.
