Modelling flow in a pipe with a glow plug
 
Hi you all,

I am experiencing some troubles modelling a problem for a research I'm working on.

The geometry is quite "simple", it consists on a cylindrical pipe with a cylinder inserted perpendicular to its axis. The cylinder simulates a glow plug, so I set its surface temperature equal to that of the plug. I am using a k-epsilon turbulent model and setting the intensity = 10% and length scale = 0.038D_pipe at both the inlet and outlet.
However, the solution is not converging and I do not know how to solve it.

Thank you all in advance!

Check to make sure your mesh is in the right units.
Check consistency of the boundary conditions.
Check your mesh quality to make sure you don't have a bad mesh.
