Velocity and other contour plots
4 Attachment(s)
Hi, I am simulating a 2D airfoil. The inlet and outlet are at 20c and wall symmetry at 15c. The solution converges, but the contour plots show strange behavior inside the domain. What may be the reason for such behavior?
I am hereby attaching the pictures of the mesh and velocity contour. Thank you. |
What's strange?

The boundary layer wall effects. High values (red zones near after the trailing edge), and low velocity values near the walls (as big blue zones). Usually the contour is smooth away from the airfoil, such as the figures attached.

It's because you have walls. Make them not walls or whatever funny boundary condition you are using.

Thank you LuckyTran for your time. I am using inlet as velocity inlet, outlet as outflow, walls as symmetry as boundary conditions. Can you please tell me where I am having wrong boundary conditions.
Thank you. |
Here's an idea, how about you actually post the settings in your BC's instead of only their type.
Did you by chance use normal magnitude velocity for your inlet instead of x-component? |
