A 1D thermal model and thermochronometer age prediction code

T_c1D - A 1D thermal and thermochronometer age prediction model

T_c1D is a one-dimensional thermal and thermochronometer age prediction model that can simulate the effects of various geodynamic and geomorphic processes on thermochronometer ages. It currently supports prediction of apatite and zircon (U-Th)/He and fission-track ages. Below you will find some essential details about using the code and detailed documentation can be found on the T_c1D documentation site.

Getting started

To get started using T_c1D you can either clone or download the source code from https://github.com/HUGG/TC1D.

Installation

In order to use the code, you should first compile the thermochronometer age prediction codes in the ketch_aft and RDAAM_He directories. From the base code directory you can do the following in a terminal:

cd ketch_aft
make && make install
cd ..

cd RDAAM_He
make && make install
cd ..

This will build the age prediction programs and install them in the bin directory. Note that you may need to edit the Makefile in the ketch_aft and RDAAM_He subdirectories to specify your compilers.

More detailed installation instructions may be available in the installation section of the documentation.

Usage

An example model with 10 km of exhumation and default values can be run from the command line as follows:

cd py
./tc1d_cli.py --ero-option1 10.0

A full list of options that can be used with Tc1D can be found by running the code with no specified flags:

./tc1d_cli.py

This will return a usage statement and list of flags the code accepts.
