Greetings!
I have a doubt about transitorial analysis. Let me explain: I´ve been looking for tutorials about the subject and I found one of CFD concerning a cylinder, I leave the link so you can check it:
www.comsol.com/showroom/downlo...e/models.mph.cylinder_flow.pdf
In this toturial a Step function is declared and is used to vary the average speed from 0 (zero) to U_mean.
My question is: Why is the funtion Step_1 used in the argument t[1/s]? According to me, we could use t[s] to obtain a "linear variation", even t would be valid as an argument to the function Step_1.
The point is, I have done this changes and the program is marking me errors.
Thanks
