Constant temperature boundary condition

Hello,
Can you please confirm how to give a constant temperature boundary condition on one face of an enclosure in flotherm XT.Am facing problems with it please help

hello,

1. add the enclosure into the "project tree" - Components (by drag and drop)
2. create a thermal attribute (thermal type -> Fixed Temperature) and choose the fixed temperature value
3. drag and drop the SmartPart "Planar Thermal Source" onto the enclosure SmartPart
4. for the thermal planar source choose the side of the enclosure that you want and as attachment chose the newly created thermal attribute.

have a nice 2017, Gabriel

Thanks a lot Gabriel,am able to solve my problem now.Can you also tell me the
where the non geometric part external wall is used ,since i was trying to simulate the effect of constant temp using external wall.i tried varying the temp of external wall to 150 C but after solving the temp of that wall is varying etween 60 to 70

hmmm...
you're doing something wrong, but I can not figure out what...

for me it looks alright, see the attached picture:
