Radiative3D

Radiative transport in 3D Earth models

Radiative3D is a 3D radiative transport software tool being developed by Christopher Sanborn and the Solid Earth Geophysics Research Group at the University of Connecticut. Radiative3D can be used to produce synthetic waveforms, travel-time curves, or volumetric visualizations of energy propagation through three-dimensional Earth models. Radiative3D uses ray tracing to simulate propagation dynamics in large-scale structure, and uses a stochastic multiple scattering process to simulate the effects of statistically-described small-scale structure. Radiative3D simulates realistic source events described by moment tensor elements, allowing it to be used to simulate a variety of focal mechanisms, including explosions, double-couple earthquakes, CLVD's, etc.

What's New:

Janaury 2020:

Added support for model architecture composed of concentric spherical shells, in which the elastic velocity profiles vary quadraticaly with the radial coordinate (v_P,S = a r^2 + c). The grid defines the velocities at the top and bottom of each spherical layer. This allows for whole-Earth models, efficiently defined in terms of a reasonably small number of layers.
Raspbian Buster on the Raspberry Pi 4 is now my primary development and testing environment. Radiative3D is fast, efficient, and runs on inexpensive hardware! Of course, it still runs great on Intel and AMD-based workstations as well.

Build Process

Radiative3D builds with GCC on MacOS (OS X), Linux, and Raspbian. (And perhaps also Windows.)

$ git clone https://github.com/christophersanborn/Radiative3D.git
$ cd Radiative3D
$ make

Results in a binary named main.

Run with:

$ ./main [args]

User Manual here: Radiative3D Manual Page

There are also supporting scripts (e.g. do-crustpinch.sh) to help with managing command line options and organizing the various output files and post-processing of data. The "do-scripts" are writtin in BASH and may depend on the installation of additional command line tools. (See Manual Page.)
