Grid Project Title: Romanian 2D Structured Grid Version 3

Purpose of Project:

To create a two-dimensional Structured grid that delineates a cross-section perpendicular
to the x-axis that runs through the well FS2. The grid will be used as part of a modeling study
to calculate flow and reactive transport, using FEHM, to help evaluate the suitability
of storing low level nuclear waste at the site. Unlike previous versions, this grid includes
stratigraphy.

conceptual model.

Grid Version: 3
Data Source: /scratch/stoshu2/Witk/Romanian/2001/Geology/Ver01/Romanian0001.tfm
Delivered To: Kay Birdsell, Bruce Robinson, and George Zyvoloski
Date Completed: 10/24/2000

Design Criteria:

Use stratigraphy from 3D Hydrostratigrahic model for material designations.
Create 100 meter domain that delineates a cross-section perpendicular to the x-axis through well FS2.
Create a structured grid with triangular elements that can be computed by FEHM.

Summary of Project:

A two dimensional grid was created with a domain that delineated a cross-section perpendicular
to the x-axis through the well FS2. Unlike the Romanian grid we received, this mesh extends north
south and contains the real world coordinate data rather than a relative coordinate system.
The grid incorporates stratigraphy from a 3D Hydrostratigraphic model for material designations. The
grid contains no negative coefficients and is computable by FEHM.
