Re: [EnergyPlus_Support] HELP WANTED



E+ is not really doing 2D or 3D heat transfer. There is a node representing the "equivalent" outside surface temperature of the wall. If the bottom of the wall is at 12C and the top is at 13C and you assume a linear propagation, then the node is at 12.5C. If it's some curve you'll have to use some mathematics to get the "equivalent".

"ground" boundry condition is the boundy temperature that the node is "against". It is also just a node, so if you have different z-height temps, you must derive the equivalent.

Doesn't the new integrated slab/basement ground couple model do this work for you?

Hi
I know that I  should split my wall surfaces but in the Field of  Outside Boundary Condition there is only one choice  for Ground While I have  different Monthly underground temperature for different Height of a single wall.

Hi

I have a question about underground wall.
how can I define different Monthly underground temperature for different Height of a single wall.
