+Conjugate Heat transfer- Pipe flow
+-----------------------------------
+
+This example illustrates a two way conjugate heat transfer case for *flow in a pipe* that is used as
+a tutorial for System Coupling. This Fluid-Structure interaction (FSI) is based on a steady case fluid flow
+in a pipe with surface data transfers.
+
+- Ansys Mechanical APDL (MAPDL) is used to perform a structural analysis.
+- Ansys Fluent is used to perform a steady fluid-flow analysis.
+- System Coupling coordinates the coupled sloution involving the above prodcuts to
+  solve the multiphysics problem via co-simulation.
+    
+**Problem description** 
+
+A fluid at a certain temperature flows into a pipe of known diameter and length. As it flows, the heated wall
+of the pipe conducts heat to the inner wall, which in turns heats the fluid and cools down the walls of the pipe.
+#image
+
+The flow is smooth inside the pipe and the outer wall of the pipe is adiabatic. Fluid enters at an initial 
+temperature of 300K while the outside pipe of the wall is at some higher temperature. The setup is simulated for 
+a few iterations to allow the examination of the temperature field in the pipe.
