This command file for running a LINUS simulation will perform multiple simulations. Each simulation output will be in a new subdirectory; sim_1, sim_2, sim_3, etc. The user should edit the "range" to set the number simulations to be run. In the example below five simulations will be run.

    for i in range(5):

Make a copy of this file in your working directory and edit it appropriately. To run a LINUS simulation see the Examples section.
