PORFLOW - #1 choice of simulation software among consultants and researchers alike in the Ground Water Flow and Nuclear Waste Management fields - is here. On top of the many stability and versatility features built into the solver, PORFLOW comes bundled with CFDStudio™, the integrated development environment for CFD applications.

Among the many other new features are:

•   º  Gridless Computing (2D only, 3D under development).(*)
•   º  Support extended to Hybrid elements such as prisms, pyramids, tetrahedra as well as hexahedra (3D); triangles as well as quads (2D). Any combination of elements are acceptable.(*)
•   º  Adaptive Gridding / Auto Refinement at runtime based on certain runtime criteria.(*)
•   º  If-then-else type of conditional statements.
•   º  Better matrix solution control.
•   º  Computational improvements for better interpolation of values at faces.

PORFLOW™ has been used to analyze problems as diverse as salinity intrusion into fresh water aquifers and remediation of hazardous waste sites. It has been used to evaluate pumping of an aquifer over a period of days, remediation of waste sites over a period of years, corrosion of waste canisters over tens of years, and transport of contaminants from nuclear waste over a time span of hundreds of thousands of years.
In the process, PORFLOW has evolved with the user's needs. At every stage, the flexibility and generality of the software were maintained while options were added to address user requirements. As a result, today PORFLOW provides a flexible format that is bound neither to a specific algorithm, nor to a particular methodology. Rather, it provides a framework that facilitates experimentation. The user can change numerical schemes, solution method, matrix inversion algorithms, or any of the physical or mathematical features.
Of all features of PORFLOW, two deserve special mention: generality of applications over a diverse range of problems, and ease of use provided by the conversational FREEFORM™ command language. These have enabled PORFLOW to emerge as leading software in its field of application.
PORFLOW is also distinguished from other computer models by the diversity of its users. Commercial, research and educational organizations in 15 countries are using the software. Among its users are: U.S. DOE, USGS, U.S.NRC, U.S.Army, Southwest Research Institute, Idaho National Engineering Laboratory, Oak Ridge National Laboratory, Savannah River Laboratory, Battelle Pacific Northwest Laboratory, ANDRA (France), SCK-CEN (Belgium), AECL (Canada), Westinghouse, Lockheed Martin, Fluor Daniel, Rockwell, and a large number of other commercial organizations. Over 100 publications and project reports on the benchmarking, verification and application of PORFLOW are currently available.
