The purpose of this Coastal and Hydraulics Engineering Technical Note CHETN is to provide guidance for automated finite-element mesh generation. This is implemented in the Automatic Mesh Generation AutoMesh tool within the Rapid Operational Access and Maneuver Support ROAMS platform. The automatic meshing procedure was developed to analyze scatter set data and produce logical finite-element mesh node connectivity without user interaction. The resultant element structure can then be used to perform hydraulic analysis in Adaptive Hydraulics AdH or other finite-element tools. Automatically generating computational meshes reduces model creation effort, lessens required user skill level, and often quickens the process compared to manual mesh creation. The automatic mesh algorithm is a critical component within the ROAMS platform, which produces rapid solutions to coastal hydrodynamics and vessel routing questions with limited information and user input. AutoMesh enables military decision makers to quickly access relevant information during logistical and combat operations in water-adjacent environments within the ROAMS platform.
