im fairly new to Anylogic and i´m trying to model a solar energy production system using the fluid library, all is well until i wanted to limit my power demand for a certain time during the day (reduction of computation power during the night), i couldn´t find a tutorial online, through some research i´ve found that i need to use either schedule or event from the agent menu, however i couldnt figure out what code to write in the actions window as i dont know the names of the variable and methods i should use.

in short i want to modify a valves´ output rate from 100% to 70% from 10pm to 6am

can anyone help

just tried different variable names and methods but none worked
