Besides enabling the 'Save channels to disk?' option under 'Project Settings\Runtime', you need to also specify inside of the PGB whether to safe only last run or all runs. (The PGB is the small graph icon from which you can add graphs and the like). Double click on a PGB and you should see the option 'Multiple Run Save'. Turn this option to 'All runs'. This setting applies to that particular PGB. Repeat for all the PGBs you are interested in.
After you run the simulation set, look inside your build folder for a file ending in *.inf. This file tells you which channel was saved to what output file.
I hope this helps.
