I am solving a three dimensional liquid jet using interFoam. I am using LES. I have a cylindrical nozzle which then opens into a cylinder. I have applied wall conditions at the nozzle walls and symmetry plane at the circumference of the cylinder. I use a velcoity inlet coniditon. at the inlet it is zeroGradient for pressure and fixed value 0 at the outlet.
But after i started my simulation, i noticed that my pressure equation is requiring many iterations to converge, and it is running for almost an hour for just one time step. My simulation has become very slow.
Anybody who had similar experience can give some suggestions on making the simulation faster.
