Point source for Thermal Engine?

Asked by Jiannan Wang

Hello,

I'm wondering is there a way to impose point or point-ish heat source for thermal engine, something similar to the point influx in the flow engine? Thanks.

Best regards
Jiannan

You can set any particle to have a desired temperature as well as a "Pcondition", which would prevent its temperature from changing during the simulation [1]. At the moment there is no way to set a single pore temperature as constant, but it would be relatively straightforward to add.

I was mistaken, I did create the ability to set a single pore with a constant temperature [1].

Hello Robert,

Thank you for the update. Maybe just a side question: what is the difference between setCellTImposed and setCellTemperature?
Thank you again.

Best regards

setCellTImposed sets it as a constant temperature condition (the
temperature will remain constant for subsequent timesteps).
setCellTemperature simply sets the cell temperature at a single step, but
it will be affected by the thermal field for subsequent timesteps.
