Convergence problems

Hello Community!
I’m having issues with my simulation converging in certain situations. I am trying to find the drag and lift coefficients at different angles of incidence towards a pentagonal cylinder for my university project. I'm new to Ansy’s fluent and I am self-learning which I must admit is proving quite difficult. For some angles closer to a corner orientation the solution converges (see the figure with the flat line for drag coefficient) well but towards the face orientation the solution does not converge well (see other figure of drag coefficient) and produces a strange discontinuity when the different angles are plotted together (see the figure with polynomial fitting). I have two questions: 1) How can I get results that fits the polynomial fitting and converges rather than the discontinuity. 2) Is there a way I can automate the process of doing these simulations for different angles? Thanks in advance, any help would be greatly appreciated! |
