LES Simulation for incompressible internal flow
 

Hi All

I am trying to do an LES Simulation for internal incompressible flow and I am getting some errors although I am intializing with zero veloctiy and inlet pressure

Also I am getting some error after initializing with the velocity and pressure as my inlet pressure


My case is
Inlet BC'n : Pressure : 6 bar
Outlet BC'n : Massflow rate : 0.058kg/sec
Ref Pressure : 1 atm
Initialization done with
u,V,w = 0 m/s
Pressure (Relative ) = 6 bar


This is what I got as an error below


_______

COEFFICIENT LOOP ITERATION = 2 CPU SECONDS = 8.578E+02
----------------------------------------------------------------------
| Equation | Rate | RMS Res | Max Res | Linear Solution |
+----------------------+------+---------+---------+------------------+

End of solution stage.

This is what I got .

Thanks
