Suppress a feature mid-simulation during transient
I have a transient study in which I turn on some heaters to heat up certain elements and then shut them down to study the temperature evolution.
Since I want to control the temperature it's much easier for me to set a given temperature to some elements (ramp up and keep a certain T for n hours), then I'd want to stop controlling the temperature of those elements, to see the evolution (there will be some radiation heat exchange and a water stream to cool down the system).
What I've been doing until now was to set two transient studies: one with an imposed temperature following the ramp and steady state, then a second identical one, getting the results from the first study, but without imposed temperature.
Is this the correct approach? Could I simply perform a single study, with a condition "suppress temperature feature" at time t? I guess this might be doable with APDL, but I've never used it (though I'm interested in learning it).
