SutraPrep Version 1.0 (3D.1) facilitates the creation of three-dimensional (3D) input datasets for the USGS ground-water flow and transport model SUTRA Version 2.0 (2D3D.1). It is most useful for applications in which the geometry of the 3D model domain and the spatial distribution of physical properties and boundary conditions is relatively simple. SutraPrep can be used to create a SUTRA main input (“.inp”) file, an initial conditions (“.ics”) file, and a 3D plot of the finite-element mesh in Virtual Reality Modeling Language (VRML) format. Input and output are text-based. The code can be run on any platform that has a standard FORTRAN-90 compiler. Executable code is available for Microsoft Windows.

Note: SutraPrep prepares input datasets for SUTRA Version 2.0 (2D3D.1), which can also be read by SUTRA Versions 2.1 and 2.2.
