Grid Project:  ASCEM F-Basin

Version History

Mesh Overview

This project is for ASCEM F-Basin Modeling. This mesh starts a triangluation based on the F-Basin shape and features; F-Basin and Barriers.The triangulated surface is used to create layer surfaces by assigning elevations equal to or relative to the DEM elevations. The surface layers are stacked and connected such that trianglular prism elements are formed between layers. Material elements (blocks) are identified to represent layers and features such as the basin and barriers. Exodus side sets are identified as boundary faces along bottom, sides, and top.

Future work may use a different boundary polygon and consider strategies for upper aquifer refinement so that elements at outlet are not so thin compared to element at outlet where layer is much thicker.

Mesh Files are available on local servers or you can download the compressed ".tar.gz" archive.

V2 Prism Meshes

The following definitions apply to all the V1 and V2 meshes:

Element type: triangular prism formed from stacked triangulated surfaces

Materials (Blocks) for all grids:
1 Bottom Layer - Lower Aquifer
2 Middle Layer - Tan Clay Layer
3 Upper Layer - Upper Aquifer (to ground surface)
4 F-Basin (one element deep at top of Upper layer)
5 Barrier 1 (2 elements wide, depth is full Upper layer)
6 Barrier 2 (2 elements wide, depth is full Upper layer)l
7 Barrier 3 (2 elements wide, depth is full Upper layer)

Boundary Side Sets (Facesets) for all grids:
faceset ss1 = bottom
faceset ss2 = east side
faceset ss3 = north inlet
faceset ss4 = west side
faceset ss5 = south side river outlet
faceset ss6 = top (minus step and features)
faceset ss7 = top step feature
faceset ss8 = top of F-Basin feature
faceset ss9 = top of Barrier 1 feature
faceset ss10 = top of Barrier 2 feature
faceset ss11 = top of Barrier 3 feature

V2 Prism Mesh with Basin and 3 Barriers Using SRS Elevations

V2.2 Input Elevations are from Haruko. Sent by email May 5 2015 in file Mesh_interfaces20150415.zip. Images showing comparisons of V2.2 and previous V2.1 surfaces are included in the Mesh and Surface QA Page.

These surface elevations do not pinchout the upper aquifer at outlet side of mesh.

V2.1 Input Elevations are from Haruko. They come from Greg's 2010 data set but are subset and converted to SRS coordinates. This conversion results in ground surface elevations that do not pinchout the upper aquifer at outlet side of mesh.

number of nodes = 199494 number of elements = 371518 Horizontal edge lengths from 50 m to 2 m near features. F-Basin edge lengths near 7 m Barriers are 2 elements wide, edge lengths of .61 m (2 ft) No pinchout, upper aquifer has 1.5m thickness at outlet. Upper Aquifer has 6 layers of proportional refinement.
