HI i have a problem of getting the Cd and Cl values and i think is due to the meshing method i use. Can anyone advise in this?
This existing results using Re=20, which calculated at velocity,v, of 0.00029m/s, with the default setting of density and viscosity. My dimension modal is 1m X 1m X 10m, which L=1m, D=10m. The boundary area is about 4D on both sides and height is also 4D from the top of the body.
Meshing method is in default setting. With this mesh i managed the iteration while calculating doesnt have any reverse flow occurs. However my Cd and Cl values are too small which considered to be zero.
I have tried many method example from the given link:
This method given a problem of having reverse flow instead.
Can anyone please advise how to get the meshing correct in order to get my results and compared with the existing results?
Anyway im doing a project to illustrate the air flow around tall buildings.
