I don’t know how. Sorry.
Something to keep in mind here: Energy Plus was created for the
purpose of modeling energy use. What you describe involves much more than
energy, and includes CFD aspects as well as the specific response of the
controls system. I don’t know what software would do this amount of
complex detail.

Subject: [EnergyPlus_Support] Re: Baseboard convective at constant
capacity
Dear James,
Thank you for your answer. However, the energy use is not exactly the objectives
of my model.
In fact, what I want is to simulate the oscillations of the air temperature of
the room because of the electric baseboard heater I have. The one I have is
connected to a thermostat which setpoints are 20 and 24°C. So, below 20°C, the
heater works at its full capacity (1000 watts) till the air temperature reachs
24°C. Then it stops until the air temperature get lower than 20°C once again.
However, with E+, I don't manage to simulate those oscillations because the
heater operates proportionally.
Do you know how I could do this?
Thank you very much for your hekp!
Augustin
