Re: Meshing in 2d analysis of incompressible flow over airfoil
I have followed the Cornell University tutorial.
I am able to generate one half of the C-Mesh successfully but not the other half.(i.e. the one which contains the rectangular domain only)
As it's necessary to make the edges biased towards the center of airfoil I used a different biasing type than the one suggested in the tutorial.
I have attached the photo of the mesh generated.
I need some suggestions on the possible solutions or the errors that might have crept in.
The biasing in the upper right corner is inconsistent.
Check again if the orientation of the edges in your model is correct.
Re: Meshing of 2d airfoil in ANSYS
I found some problems in my geometry and rebuilt it. http://www.mne.psu.edu/cimbala/Learn...al_Airfoil.pdf
This is the tutorial I followed for geometry. While Meshing the C-domain, my aim was to keep the edge biased towards the center of the airfoil.
I feel that mesh in the circular domain is not "perfect". Could anyone give their views regarding this mesh?
How can it be improved?
What is the meaning of "The default defeaturing tolerance was larger than one computed based on size controls. The mesher has modified the global defeaturing tolerance accordingly."?
Thanks in advance,
Basically this means that the Ansys mesher is not intended to do this kind of meshing. Dont worry about the notification.
Switch of the advanced sizing functions instead.
Thank you. I will do that and try improving the mesh
