Description: The Naval Research Laboratory (NRL) has developed the NUMCAT™ suite of powerful, easy-to-use tools to support application of the open source ADvanced CIRCulation (ADCIRC) model. ADCIRC simulates currents, water level, storm surges, temperature, and salinity in the coastal ocean including regions of shallow shelf waters, estuaries, and rivers. The NUMCAT™ tools can be modified to support other finite element based models. Such models require a complex set of input files and parameters, and the NUMCAT™ software toolset makes the development of those inputs easier. The NUMCAT™ toolset can generate or edit an unstructured mesh of triangular elements, facilitate the specification of a model input parameter file including periodic (tidal) boundary forcing, and assist in creating model forcing files associated with meteorological forcing. The entire NUMCAT™ software suite is designed to aid a non-expert in the set-up and application of the ADCIRC model with minimal user knowledge and intervention. The NUMCAT™ toolset is currently in use by the Naval Oceanographic Office to support prediction of coastal currents and water levels.

Advantages/Features Include:

  • Automates generation of an unstructured mesh of triangular elements
  • Allows mesh editing and visualization
  • Relational and error checking for model set-up
  • Runs on various platforms/operating systems
  • Estimates CPU resources required for a created mesh
  • Estimates time step size required for model simulation
  • Modular design accommodates new forcing data sources
  • User friendly graphical user interface
  • Easy to use; no formal expertise is required
