Make Grid

Create a regular 3D grid, and query UCVM for properties on the grid

(Python2) [maechlin@1a1dea59d47e target]$ cp ../make_mesh.py .
(Python2) [maechlin@1a1dea59d47e target]$ ./make_mesh.py
Creating grd.out file.

Generating grid

This will run a script that creates a 300K input data file called "grd.out" and writes it to the "target" directory. Then the make_mesh.py script uses that file to query each SCEC velocity models. Only queries for the "selected" CVM (in this case "cvms5") will succeed in this script. However the script provides a good example of how the UCVM Images can be used to extract properties for a moderate number of points.

make_mesh.py outputs

UCVM Docker images use the make_mesh.py as a test script. When run, it builds a grd.out file that discretizes the western US (this can take 20 minutes). Then make_mesh.py queries all avialable UCVM models using the grd.out grid point file.

When users runs make_mesh.py it queries 1D models and then each available 3d model. Only the 3D model installed in the UCVM Docker image should succeed. Below is an example of running make_mesh.py in a "cvms5" UCVM Docker image.

Example Use Case

The Docker images contain a two part test program. Using a user on a Mac, with Docker installed and running, here's how to run the UCVM Docker image.

• User moves to ucvm_docker directory on their Laptop cd /Users/maechlin/ucvm_docker

• User reviews is currently in "target" directory, the file exchange directory between Laptop and Container. ** pwd /Users/maechlin/ucvm_docker/ ** ls target

• User starts UCVM Docker image that will ** ./start.sh

The UCVM Linux shells starts, and the User is placed at a command line prompt in a directory called: /app/target

[ucvm@65b00f2cf0e2 target]$ pwd
/app/target
[ucvm@65b00f2cf0e2 target]$ ls
[ucvm@65b00f2cf0e2 target]$

Copy a script from the container to target directory.

• cp /app/make_mesh.py .

The run the script to generate an input mesh for ucvm:

• ./make_mesh.py

This will generate a 100,000 mesh point input file in your target directory. This is a moderate query for ucvm. Now query the available model this way.

./ucvm_query -f /app/ucvm/conf/ucvm/conf -m cencal < grd.in > grd.out

This will run and output a grd.out file that has all the colums from grd.in and it add 3 new columns vp, vs, and rho for the given point.
