DOUAR is a fully coupled 3D thermo-mechanical model. It can be set to model a large number of tectonic scenarios and can be adapted to other settings with reasonable effort. It includes erosion by Cascade or FastScape, particle tracking and thermochronometric age prediction, sediment compaction and more.
For access to the code, ask David Whipp for access to the DOUAR Git Repository. Input files and examples can be found there as well.
A short intro for how to compile and run DOUAR can be found in the HUGG wiki.
