At present my time step is 5e-08 and after 7860 iteration the flow time is only 0.001366s seconds and it seems like it is taking an eternity to run and due to a lack of licences this is a major problem.
I was wondering if I have maybe made a mistake in setting up my simulation and I would be very grateful for any help given.
My mesh is a simple rectangular channel 0.55 meters by 6 meters. The mesh spacing is 0.005.
My solver settings are: 2d, segregrated, implicit, time - unsteady, velocity - absolute, 1st order, cell based, superficial.
Multiphase - Volume of fluid. 2 phases; air and water, water patch into region.
K-epsilion viscous model used. Momentum and Energy models not changed.
Operating conditions - Pressure located at top of mesh. Gravity is on on with X=0 m/s-2 and Y = -9.81 m/s-, specific gravity = 1.225.
Boundary conditions - all verticies are walls.
The turbulent velocity is 0 and in the solution control- Pressure discretization is standard and PISO is the Pressure-Velocity Coupling method.
