Grid Project:   CO2 Incline

Mesh Team Members: Terry Miller
Modeling Team Members: Rajesh Pawar
Delivered: October 2018
Local Working Directory: /scratch/fwo/tam/CO2

Project Purpose

Investigate movement of CO2 plume with an up slope near 6 degrees and near 25 degrees on the back side.
This simulation is extremely sensitive to the smoothness of the slope along x,y,z.

V1 Rock Springs Uplift

V1 RSU MESH using Rock Springs Uplift surface 
See 2008 Project pages https://meshing.lanl.gov/proj/WYCO2_2008/catalog.html

Mesh is 200000 long x 7000 wide with Z from 0 to 5350 meters. 
Middle Material 2 has 50m horiz spacing and 30m spacing same as stack_slope_v3 and 4a

Note this surface has almost 300m spacing and extents to not extend far
enough south to include the full hump. This mesh front is at furthest south edge.

V3c 6 degree Rotated Incline

SLOPE MESH V3c 50m with 30m vertical layers in middle 
Replaces V3a which has a subtle problem at the join
Replaces V3b with join point translated to nearest 50m integer 

/scratch/fwo/tam/CO2/stack_slope_v3c
684275   nodes    
3887436  tets

Mesh has consistent 30m layers for material 2 and the neighboring buffer layers.
So all Voronoi volumes for material 2 are within an epsilon of 75000 (not boundary).

140000 long x 5000 wide with 50m horiz spacing and 30m spacing in middle material 2. 
This mesh fixes the slope so it has a smooth transition from the straight incline to the hill.
The voronoi volume inconsistency is fixed with wider buffers.
This version has a 6 degree incline joining 6 deg sin wave then a 25 degree sin slope at east end.

V2 6 degree Rotated Incline

Sep 13 2018 Local: /scratch/fwo/tam/CO2/stack_slope_v2
SLOPE MESH V2 40m vertical spacing

140000 long x 5000 wide with 50m horiz spacing and near 40m vertical spacing
This version has a 6 degree incline merged at top with 25 degree wave slope at east end
The first effort was close to 45 degrees and could not connect without popping tets

number of nodes =      596001
number of elements =   336000

Material 3 = Above slope layer with flat top at 2000
Material 2 = Slope layer 400m thick with 40m divisions
Material 1 = Under slope layer with flat bottom at 0
