3. DESCRIPTION OF PROGRAM OR FUNCTION

NORIA is a finite element program that simultaneously solves four nonlinear parabolic, partial differential equations that describe the transport of water, water vapor, air, and energy through partially saturated porous media. NORIA is designed for the analysis of two-dimensional, non-isothermal, unsaturated porous flow problems. Nearly all material properties, such as permeability, can either be set to constant values or defined as functions of the dependent and independent variables by user-supplied subroutines. The gas phase is taken to be ideal. NORIA is intended to solve nonisothermal problems in which large gradients are expected in the gas pressure.

4. METHOD OF SOLUTION

NORIA uses the standard Galerkin finite element method to handle spatial discretization of two-dimensional domains with either planar symmetry of axisymmetry. Time integration is performed by a third-order predictor-corrector scheme coupled with Newton iteration that uses error estimates to automatically adjust time-step size so as to maintain uniform local time truncation error throughout the calculation. An Adams-Bashforth' predictor is combined with a Crank-Nicolson corrector step for each time-step after the initial two. Four basic finite element types are available in NORIA: isoparametric 8-node quadrilateral, subparametric 8-node quadrilateral, isoparametric 6-node triangle, and subparametric 6-node triangle.

6. TYPICAL RUNNING TIME

As a rule of thumb, NORIA requires about 10 seconds for compilation and start-up and about 0.075 seconds/element/time-step for solution of the differential equations. More time should be allowed for problems with 200 or more elements, and 10 to 20 seconds should be added if significant postprocessing is to be performed, such as computing heat fluxes, computing velocities, or plotting.

8. RELATED AND AUXILIARY PROGRAMS

NORIA is one of a family of SNLA finite element codes that includes COYOTE, NACHOS, MARIAH, and SAGUARO. Other programs that can solve the same type of problems as  NORIA include the Sandia National Laboratories PETROS program, the Lawrence Berkeley Laboratory TOUGH program, and the Los Alamos National Laboratory WAFE program.
