UCVM 13.9.0 Advanced User Guide

Overview

This guide is intended for users looking to use the advanced features of UCVM. Most common functionality, including mesh generation and getting material properties from models, is described in the main user guide.

UCVM 13.9.0 was released on September 8th, 2013 and is the latest version of the Unified Community Velocity Model (UCVM) framework available. UCVM is a collection of software utilities that are designed to make querying velocity models, building meshes, and visualizing velocity models easier to do through a uniform software interface. UCVM has been used extensively to generate meshes and e-trees that are then used for 3D wave propagation simulations within California.

This guide describes some of the more advanced features of UCVM, such as the ability to add a custom Vs30 GTL, combine models, and install models other than CVM-S4, CVM-H 11.9.1, CVM-S4.23, and CenCal.

Installation

If you would only like CVM-S4, CVM-H 11.9.1, CVM-S4.23, and/or CenCal, we strongly recommend following this installation guide.

The first step to installing UCVM is to download the latest UCVM distribution. Then, you will need:

• Proj-4 version 4.8.0
• Euclid-3 version 1.3

If you would like to export to NetCDF format, you will also need the NetCDF library.

• NetCDF

You will also need to retrieve the desired community velocity models. Currently, the following models are supported in UCVM 13.9.0:

• CVM-S4
• CVM-H 11.9.1
• CVM-S4.23
• CenCal
• SCEC CVM-NCI
• Magistrale Wasatch Front CVM
• Graves Cape Mendocino
• Lin-Thurber Statewide
• Tape SoCal
