Ansys Forte: fuel not burning.

  Hi everyone,
  I am currently working with forte for my diploma thesis and I 'm trying to simulate a marine diesel engine. I started by creating a sector mesh of the cylinder and also a more detailed model including valves, intake manifold and exhaust. The second simulation is currently running. Regarding to the first one I have an issue as the fuel does not burn. I have calculated the fuel mass and all the initial conditions. Any help or suggestion would be welcome.
  Thank you in advance.

  Hi,
  There is an example in Forte tutorial which you can refer for guidance on sector modelling of Diesel engine combustion.
  Chapter 2: Simulating a Diesel Engine Using a Sector Mesh
  Also what is the current sector angle you are considering (how many nozzle holes are there in the injector). Since the simulation with full geometry is working - I'm assuming your chemistry file and chemistry setup should be correct.
  What is the pressure and temp rise during the compression stroke and are the fuel getting vaporized completely ? These would help in figuring out the issue on why the combustion is not happening.
