Generate a mesh for the 3-D model (from EV jb3delev geology and data) sent by John Jiao, WSGS
. The mesh will represent an injection well in the middle of the survey to evaluate how much CO2 could be
injected to Weber Sandstone and Madison Limestone.
The high resolution units include Madison, Amsden, Weber, Phosphoria, and Dinwoody. The bottom unit, Darby, and the top combined units are thick units with the largest spacing. The mesh has a target of 6m vertical spacing in the high res units, with an upper limit of 300,000 total mesh nodes. The well is represented by a column of nodes with same vertical spacing as rest of mesh, and minimal horizontal refinement to keep the total number of mesh nodes below the limit.
The Wyoming EV model consists of Jim Bridger structural jb3delev framework, and porosity and permeability data in jb3delev_perm and jb3delev_por.

The porosity and permeability values are imported from sets of scattered point values into Earthvision and applied to each of the intervals. For this mesh, the input por and perm values are at a fine enough resolution to use interpolation directly from the input data. This skips the step of previous MOXA model which used EV to interpolate sparse data on to the EV model, then interpolated on to a set of fine resolution points - and then used upscale on to the mesh.
The input *pdat files for the EV model is used directly to interpolate perm and por values on to the computational mesh using LaGriT. The EV perm and por values of the input data points are found such that they are located on or inside the Voronoi volume and then applied to the corresponding mesh node.
PERM and POR Data
local directory /scratch/fwo/wyo_ev_models/EV3D_MAR_2012_elev_PorPerm/
perm and por values are on regular spaced x,y of 134.10 meters
z values for each unit have 230 points spread between bot and top unit surfaces
ie, for target units with thickness of 128 m, the points are 6m apart

Step 1) Create template with quad background and embedded well using LaGriT scripts
/scratch/fwo/tam/wy_2012/grid_template
Spacing is 150m, 75m in well region, 37.5 at well location.
This template has least number of nodes possible to allow high res stacking.
Change well coord to integer number and translate template
such that well center is aligned along column of background mesh
well coord 148710, 116175
Step 2) Create material zone surfaces using LaGriT interpolate
Extract top material elevations from EV and interpolate on to template locations.
/scratch/fwo/wyo_ev_models/EV3D_MAR_2012_elev
Run script foreach zone, use ev_hgbak and lagrit to write surface files.
run_layers.scr
Step 3) Create stacked layer computational mesh
/scratch/fwo/tam/wy_2012/grid_stack
Stack the material surfaces extracted from EV into layers with vertical spacing as near
to 6 meters as possible for important zones (2-6). Keep total number of nodes below 300,000.
lagrit < stack.lgi
Note: manually creating offset surfaces creates fully conforming interfaces
the stack method will result in column oriented voronoi volumes
Step 3) Connect stacked points into Delaunay tet mesh.
grid_stack/connect_pyramid
The high ascpect ratio causes connect/delaunay to pop connections into bad ccoefs
Use the pyramid algorithm to connect with higher precision and 0 bad ccoefs
Note the 7m resolution is the mininum before bad ccoefs result, 10m gives best result.
This mesh is at the 7 m resolution and does not have interface points removed.
Step 4) Apply perm and por values on to the mesh using LaGriT EV input data.
Upscale method is not used as input data has 6m resolution, good for interpolation.
This allows for faster completion and avoids extra interpolation steps and appears
to be visually appropriate, and in particular, the well area looks good.
Use perm and por input data /scratch/fwo/wyo_ev_models/EV3D_MAR_2012_elev_PorPerm
jb3delev_perm/*pdat and jb3delev_por/*pdat
For each mesh node of each material, apply perm or por value
where src_val(i to n) are all source nodes found within the Voronoi cell of the sink node.
/scratch/fwo/tam/wy_2012/fehm_grid_stackv01/pdata
lagrit < interp_perm.lgi
lagrit < interp_por.lgi
Step 5) write final fehm files and the perm and por attributes for the mesh
/scratch/fwo/tam/wy_2011/fehm_grid_vers02
lagrit < fehm_files.lgi
/scratch/fwo/wyo_ev_models/EV3D_MAR_2012_elev/jb3dele.seq /scratch/fwo/wyo_ev_models/EV3D_MAR_2012_elev_PorPerm/jb3delev_perm/perm*input.pdat /scratch/fwo/wyo_ev_models/EV3D_MAR_2012_elev_PorPerm/jb3delev_por/por*input.pdat

Use the same surfaces as used for the refined tet mesh, but without the refinement. The result is a hex mesh with the same spacing as the background version of the refined tet mesh. Horizontal spacing is 150 meters. Vertical is variable and based on layers in relation to the Earthvision surfaces. Mesh extents (meters) are the same as the tet mesh.

Brick Mesh Zone Materials 
|
This is a quick and coarse version of the mesh with 300x300x25 regular spacing for scoping purposes. Interpolate
was used for perm and por values instead of the more complicated upscale method.
This Brick Mesh was created using LaGriT input files and Earthvision on the command line to query material zone values for the mesh point locations.
number of nodes = 58444 number of elements = 323089
This scoping mesh is regular spacing with vertical refinement to well node
300 x 300 meter horizontal, refined by halves to well area with
25.33 vertical resolution. Well nodes are tagged as closest column to actual location.
Well coordinates for this coarse mesh are at 148687.50, 116187.50.
