Abstract: The Environmental Modeling Research Laboratory (EMRL) at Brigham Young University in partnership with the U.S. Army Engineer Research and Development Center (ERDC) is currently developing a generic data format for multi-dimensional models. The goal of this exercise is to develop, promote, and deploy a common modeling format that facilitates data storage, exchange, access, analysis, and discovery of scientific and engineering data. The project encompasses one-, two-, and three-dimensional models including river cross-sections, scatter points, unstructured (finite element) grids, and structured grids. The objective of the project is to define a standard file format for all computational models developed at ERDC. The new model format is called XMDF (for Generic Model Data Format) and consists of a file format and an object code library (Application Programming Interface (API)). The API consists of a series of subroutines in both C/C++ and FORTRAN that can be used to read and write model geometry and data sets to the XMDF format. Model developers within ERDC will be encouraged to adopt the format for all existing and future models. Numerous benefits will be derived from the standardized model format including highly compact and efficient file i/o. Using a common format makes it possible to easily share data between models, link models, and gain access to powerful visualization tools.
