Problem with Grid convergence study
I am simulating 5 degree slice of a cylinderical reactor having two inlets at the top face of the slice, one for solid fuel & one for oxygen inlet, and an outlet at the bottom face of the slice. This model has two symmetry face and the rest are walls.
I have created three meshes using CFX-mesh for my grid convergence study. I have used global mesh scaling factor, point control and infilation to generate three meshes for my study. However, the solutions from the three meshes are not consistent meaning, the solutions are not in increasing or decreasing order. I have tried quite a lot of time and problem persist. Is there any one who colud give me peaces of advice.
This means you are not in the convergent section of the mesh sensitivity scale. You need a finer mesh again until the results start to be convergent.
