STOMP Subsurface Transport Over Multiple Phases: Application guide

Abstract

This Application Guide is a software document written to provide a suite of example applications of the STOMP (Subsurface Transport Over Multiple Phases) simulator, a scientific tool for analyzing multiple phase subsurface flow and transport. A description of STOMP'S governing equations and constitutive functions and numerical solution algorithms are provided in a companion document, the STOMP Theory Guide. The use, compilation, and execution of the STOMP simulator are described in a second companion document, the STOMP User's Guide. Creation of input files for the STOMP simulator with the sTeP utility is described in a third companion document, the sTeP User's Guide. In writing these guides to the STOMP simulator, the authors have assumed that the reader or code user has received training or is knowledgeable on the topics of multiple phase hydrology, thermodynamics, radioactive chain decay, and nonhysteretic relative permeability-saturation-capillary pressure (k-S-P) functions. The authors further assume that the reader is familiar with the computing environment on which they plan to compile and execute the STOMP simulator. Computer requirements for the STOMP simulator are strongly dependent on the complexity of the simulated system and the translation of the physical domain into a computational domain. The simulator requires an ANSI FORTRAN 77 compiler to generate an executable code. The speed at which the STOMP simulator solves subsurface flow and transport problems depends on the computing platform, problem complexity, and computational domain size and dimensionality. One-dimensional problems of moderate complexity can be solved on conventional desktop computers, but multidimensional problems involving complex flow and transport phenomena typically require the power and memory capabilities of workstation or mainframe computer systems.

STOMP Subsurface Transport Over Multiple Phases Version 2.0 Theory Guide

“…It has been written to provide users of the STOMP simulator with information about the solved governing and constitutive equations, numerical algorithms, and solution techniques. The second companion document, the STOMP Applications Guide [Nichols et al 2000], provides users of the STOMP simulator with applications of the simulator to classical groundwater problems. The third companion document, the STOMP User Guide , provides users of the STOMP simulator with necessary information for selecting an appropriate operational mode, understanding the code flow path and design, creating input files, dimensioning the executable, compiling and executing, and interpreting simulation outputs.…”

Development of Radon-222 as Natural Tracer for Monitoring the Remediation of NAPL in the Subsurface

“…STOMP is a fully implicit volume-integrated finite difference simulator for modeling one-, two-and three-dimensional flow and transport, which has been extensively tested and validated against published analytical solutions as well as other numerical codes (Nichols et al, 1997). The computational domain consisted of a line of 250 nodes with a uniform radial node spacing of ∆r = 1.0 cm.…”
