Hi,
I am simulating heat transfer with fluid flow, thus I need to slowly increase my heat source to make my simulation works. Until now I've been using step function but I feel liek ramp function fits it better. Id like to have my heat source value increasing from 0 to 100% in 20% of the time of simulation, then to stay at this level.
I'm not sure if I am doing correctly. For example, I have my heat source 1000 kw/m3 and 300 s time simulation. Should I set slope as: 1000/0.2*300 and cutoff: 0.2*300 ?
And then set my heat source as 1000*rm1(t[1/s])?
I appreciate any help cause I'm little confused now.
