image description image description image description image description image description image description image description image description I set the plant loop as the first two figure, the internal source as shown below, the setpoint manager like the following three figures. after running the simulation I have no fatal error and you can see a power consumption for heating, but looking at the indoor temperatures seems like nothing warms up. I'm sorry if i inserted too many images. someone has a suggestion to give me?

I tried to delete the first three layers of the internal source and now it works. the internal temperatures follow the schedules set. now I wonder why. if you have an explanation I would be interested in understanding how the software works

for information: the energy consumption is now half (58,2 kBtu)

Beware than in the Internal Construction you also have fields below the material list, the ones described here.

but in openstudio where do I have to set these fields?

Under Construction tab, click on your construction, and scroll down like I said.

SO are you succeed in modeling a radiant floor heating system? I am trying to do it, but it is very difficult, would you please share a simple example? Thank you sosososo much!
