Heat Flux from warm water ...
 
Dear users ... Model : pipe 18/16 mm. Inside is runing warm water with 90 degrees of Celsius.On the pipe is metal sheet with 0,2 mm thicnkess. I would like to simulate charakteristic of temperature to distance from surface pipe-metal sheet. Problem : I don't know, what kind of boundary conditions are metal sheet, pipe. I solved this was : (2D) Pipe is "wall" with heat flux about 70 W/m2, 340 K, thickness 1 mm, material (Cu) with constant thermal conductivity. Metal sheet is "solid" with initialize temperature about 395 K. After starting iterate, iterating finished in 5. steps like convegency solution. Then Fluent tell me any error in file, which is compile in C (I mean C++) Please, advise me with this problem Thank you!
