hi everyone
i'm silulation an U-pipe which containing a fluid and both of them are in the soil. so there is three part (2 solids and a fluid)
the pipe has a small thickness. is there anyway to don't mesh the pipe and only assume it's conduction is ansys fluent ?
i try to use shell conduction but because of conjugate heat transfer and interface boundry condition in fluid and soil's wall i couldn't use that . is there anyway else ?
thanks
Hi Reza,
Shell conduction is the common method to deal with such problems. I am bit confused why its not working in your case. Is it that you are facing divergence issue with shell conduction. If so, switch off the second order term for energy equation at the wall.

dear rajesh
thanks for your answer
when i use shell conduction between fluid and soil as a pipe part and i give a boundry condition to the outer side of the soil, the conduction in the soil occur but the convection in the water doesn't occure. what's the problem ? ( i don't have this problem when i use interface boundry condition at the wall of the fluid and soil )
regards
