Spray injection and errors
i'm trying to simulate a spray injection in a chamber (a cube).
I'm new with star-CD, also what can you suggest who can help me ? (model or other tipps)
I have parametrized a simulation with droplet atomization and break-up, with a k-epsilon model, there is just a static air in the chamber before the injection (a flow will come in the future, also there are no inlet and no outlet just a wall). I would like to see the spray.
But when I start the simulation, I have an error :
BEGINNING CELL TO WALL DISTANCE CALCULATION
***ERROR #018 *** NO WALL BOUNDARIES SPECIFIED FOR TWO LAYER MODEL APPLICATION
What's going wrong ?
I thank you in advance
My guess is you requested a Low-Re model. Either switch to a High Re model or grid your model for Low-Re & specify which wall boundaries you want to have Low-Re treatement.
the characteristics of my chamber are :
chamber pressure = 60bar
chamber temperature = 800K
injection pressure = 1000bar
injection temperature = 340K
and no flow in the chamber.
Why a low Re model at first ?
why have I an error "no wall boundaries specified" ? I have just created a simple cube grid. What's the problem ?
Thanks already for your answer
Try "twol, off".
