Problem on the JacchiaRoberts Model

[M.delbourg]

Hello everyone,

I am currently trying to do the GMAT tutorials in order to learn how to use the software. unfortunately, the JacchiaRoberts model doesn't seem to work.
I am following the steps of the first tutorial: Simulating an Orbit and when I want to validate the settings it tells me that the Schattenfile is missing. I go into setup for the JacchiaRoberts model and both the space weather and schatten file are missing and I can't validate the setup without them. Do I need to download these files or is there another way to do the tutorial ?

Thank you for your help.
