FLUENT 12.1 - Steady Flow Past a Cylinder - Solution

5. Solution

Second Order Upwind Momentum Scheme

Solution > Solution Methods > Spatial Discretization. Set Momentum to Second Order Upwind

Convergence Criterion

Solution > Monitors > Residuals > Edit.... Set the Absolute Criteria for , x-velocity and y-velocity all to 1e-6. Click ok

Solution > Monitors > Drag > Edit.... Then check Print to Console and Plot. Next, click cylinderwall, which is located under Wall Zones. Lastly, click ok

Solution Initialization

Solution > Solution Initialization. Set Compute From to farfield1. Alternately, you can simply set X Velocity to 1 m/s. Then, click Initialize.

Iterate Until Convergence

Solution > Run Calculation. Set the Number of Iterations to 2000. Then, click Calculate. (You may have to hit Calculate twice.) Now, have a cup of coffee. The solution should converge after approximately 1634 iterations.
