(updated: this edition has been verified against the current EDVDS source (Physics/Source/Edvds/, including Vdsinput2.cpp) and the current HVE user interface resources. Notable updates: the Tire Model Method calculation option is Linear (default) or Semi-Empirical — the Table Look-Up option is disabled in the dialog and rejected by the physics program; the terrain (GetSurfaceInfo) search options have moved to the separate Get Surface Information Options dialog, where the By Elevation method is unsupported; and the message catalog has grown from 7 to 12 messages. See the individual chapters for details, and the EDVDS Calculation Options reference for the current dialog.)

How to Use This Manual¶

This manual is the user's manual for the EDVDS simulation model. The manual describes the model features and use. Input parameters and output reports are described at a high level. This manual is intended to be used in conjunction with the HVE User's Manual. The HVE User's Manual provides in-depth coverage of the human, vehicle and environment models, as well as the HVE Event Editor and Playback Editor. For specific model definitions, the user is referred to the HVE Operations Manual.
