Hi,
I'm assuming the simulation method in the tutorial calls for a scripted flow, where you write your own .do file. This tutorial gives a quick-start on how to perform simulation on ModelSim: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/archives/ug-20093-17-0.pdf?wapkw=quick-start%20quartus%20pro
What you can do is use the .do file from the tutorial as a template and then edit to however you like.
A simpler simulation method is using the NativeLink flow, where you design and save the project on Quartus, then run an RTL simulation hence invoking ModelSim through Quartus. This way the .do file will be generated automatically. Here is the tutorial for that: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/archives/ug_gs_msa_qii-17-0.pdf?wapkw=quick-start%20quartus%20standard
