3D Cartesian Rift#
A simple setup of a rift in a Cartesian box, in which two plates are spreading at a constant spreading rate. The files can be found here.
The relevant part of the World Builder file looks like this:

And the generated output model looks like this:
The 1000 K temperature isosurface of the 3D Cartesian rift cookbook. Colors represent the depth of the isosurface in meters and the black box represents the boundaries of the model setup.#
