ITOUGH2 sample problems
Abstract
This report contains a collection of ITOUGH2 sample problems. It complements the ITOUGH2 User`s Guide [Finsterle, 1997a], and the ITOUGH2 Command Reference [Finsterle, 1997b]. ITOUGH2 is a program for parameter estimation, sensitivity analysis, and uncertainty propagation analysis. It is based on the TOUGH2 simulator for non-isothermal multiphase flow in fractured and porous media [Preuss, 1987, 1991a]. The report ITOUGH2 User`s Guide [Finsterle, 1997a] describes the inverse modeling framework and provides the theoretical background. The report ITOUGH2 Command Reference [Finsterle, 1997b] contains the syntax of all ITOUGH2 commands. This report describes a variety of sample problems solved by ITOUGH2. Table 1.1 contains a short description of the seven sample problems discussed in this report. The TOUGH2 equation-of-state (EOS) module that needs to be linked to ITOUGH2 is also indicated. Each sample problem focuses on a few selected issues shown in Table 1.2. ITOUGH2 input features and the usage of program options are described. Furthermore, interpretations of selected inverse modeling results are given. Problem 1 is a multipart tutorial, describing basic ITOUGH2 input files for the main ITOUGH2 application modes; no interpretation of results is given. Problem 2 focuses on non-uniqueness, residual analysis, and correlation structure. Problem 3 illustrates a variety ofmore »

Parallelization of ITOUGH2 using PVM
ITOUGH2 inversions are computationally intensive because the forward problem must be solved many times to evaluate the objective function for different parameter combinations or to numerically calculate sensitivity coefficients. Most of these forward runs are independent from each other and can therefore be performed in parallel. Message passing based on the Parallel Virtual Machine (PVM) system has been implemented into ITOUGH2 to enable parallel processing of ITOUGH2 jobs on a heterogeneous network of Unix workstations. This report describes the PVM system and its implementation into ITOUGH2. Instructions are given for installing PVM, compiling ITOUGH2-PVM for use on a workstation cluster,more » -
ITOUGH2 V3.2 verification and validation report
This report describes the Verification and Validation (V and V) test cases performed to qualify ITOUGH2 V3.2. ITOUGH2 V3.2 was installed in a directory {approximately}/itough2v3.2 on a SUN ULTRA 1 workstation under UNIX Solaris 2. Instructions for installing ITOUGH2 can be found in file read.me and the user`s manual. This report is structured as follows: for each functional requirement, the corresponding design is described, which may include the mathematical model implemented in ITOUGH2 V3.2, if appropriate. Next, the author discusses the test case or sequence of test cases performed to validate each requirement, followed by a description of the testmore » -
ITOUGH2 software qualification
The purpose of this report is to provide all software baseline documents necessary for the software qualification of ITOUGH2. ITOUGH2 is a computer program providing inverse modeling capabilities for TOUGH2. TOUGH2 is a numerical simulation code for multi-dimensional coupled fluid and heat flow of multiphase, multicomponent fluid mixtures in porous and fractured media. -
ITOUGH2 command reference. Version 3.1
This report contains a detailed description of all ITOUGH2 commands. It complements the ITOUGH2 User`s Guide and the collection of ITOUGH2 sample problems. ITOUGH2 is a program for parameter estimation, sensitivity analysis, and uncertainty propagation analysis. It is based on the TOUGH2 simulator for non-isothermal multiphase flow in fractured and porous media. Extensive experience in using TOUGH2 is a prerequisite for using ITOUGH2. The preparation of an input file for TOUGH2 or its derivatives is described in separate manuals and is not part of this report. The ITOUGH2 user`s guide summarizes the inverse modeling theory pertaining to ITOUGH2, and describesmore »
