Scaling up the use case

[Kirismarna]

Hello,

First of all thanks for sharing this tool. I'm using it as a part of my thesis.
I'm trying to use the optimization of fluid and thermal flow, but for a scaled up domain, velocity and heat flux.

However after much trial and error, even when lowering the velocity for the larger domain to keep the same Reynolds number, I can't get the optimization to work. It seems like the thermal sensetivities are too low or something similar.

I would like to ask if you have some parameters in mind which should changed when scaling up, and if you remember the behaviour of the tool when scaled up or if it is even possible.

Lastly, I noticed that the heat flux used in the 2D case is in W/m2 (the value shown in your paper). However, isn't the heat flux volumetric in this tool? As such shouldn't it be adjusted by the cell heights?

Thank you in advance

Best regards,

Giorgos
