Test Cases Mesh and Grid

${UCVM_INSTALL_PATH}/utilities

Tool commands

The ucvm_bin/utilities directory contains couple of utility tools

• makegrid.sh - A tool that creates an ASCII grid file with 3272481 mesh points for a large region of western US and writes it to file grd.out.
• makemapgrid.py - A tool that generate a set of grid points and retrieve material properties with ucvm_query and write the result to a txt file

makegrid.sh

This utility creates an ASCII grid file with 3272481 mesh points and writes it to file grd.out. This can take 30 minutes to complete when you run it.

• Starting Directory: ucvm installation/utilities
• Usage: ./make_grid.sh

The grd.out file is used as input to the make_mesh.py script. That script inputs the grd.out file and queries each velocity model for material properties at each of the grid points. It also times how long it takes to do each retrieve.

• HOR_SPACING=0.1
• VERT_SPACING=250
• MIN_DEPTH=0
• MAX_DEPTH=20000
• MIN_LON=-130.0
• MAX_LON=-110.0
• MIN_LAT=26.0
• MAX_LAT=46.0

Test Grid Coverage Region

TEST commands

The ucvm_bin/utilities directory contains several test scripts

• make_mesh.py - A script that generates a big mesh and query installed crustal models and time how long it takes to populate a given large grid

make_mesh.py

This utility will input the out.grd file, and query each velocity model and time the results.

Running make_mesh.py to Test Speed to populate grid from different CVM

• First, the script calls ./makegrid.sh to create an out.grd file that will be used in the next step. This is a time consuming script that makes a mesh for a large region of western US.
• Next, ucvm_query is invoked like this one:

../bin/ucvm_query -f ../conf/ucvm.conf -m %s < ../utilities/out.grd > mesh_%s.out

Inputs the out.grd file and creates and mesh_[cvm_name].out that has material properties assigned. The grid/mesh is 32 million points.
