Divergence error-Pls help
 
Hi all,

I am trying to solve a simple distribution pipe problem using steam as my working fluid.
I tried my problem with Density based solver,using Pressure inlet and pressure outlet boundary condition, since i dont have the mass of fluid entering the pipe and velocity of the fluid.When i tried to solve for a few iteration with the above said set up's i go the following error

"Internal error at line 1387 in file '..\..\src\rp_mstage.c'.
Divergence detected in AMG solver"

got no clue of what is it exactly related to , is it related to my boundary conditions set ups or is it related to urf values.

It will be really helpful if someone could sahre their view in this regards,

cheers...
kumar.
