Can anyone help me ..
I want to build a geometry of a airfoil with flap, mesh it Gambit and analyze it with Fluent. can i get direct co-ordinates of such case so that i can change the angle of flap only with respect to airfoil keeping angle of attack constant? if it is possible pls tell me the details.. Thank u ... |

For fixed mesh only

for fixed mesh only.. i would like to compare results of an airfoil with different flaps.(for example NACA4412 airfoil with NACA 4412 flap , and NACA 4412 airfoil with NACA 23015 flap) please tell me how should i proceed forward.
ThanQ for the replies |

-Create your outer domain
-Create your multi element airfoil. -save this dbs >> save this session with another name Now you can go and substract airfoils domain from outer domain Finally mesh For other flap incidence, load the other dbs, rotate your flap, substract, etc... it is just a copy paste...........

you need first to get airfoil geometries

finally i did meshing for the airfoil with a flap , now i imported it into fluent
, ( i am attaching the mesh image here under). now i gave pressure far field for all the boundaries . i gave mach number 0.2 i am using RNG k-epsilon turbulent model to solve it. i gave option to plot and write Cd and Cl ( co.efficient of lift and drag). when i solve with the above options i am getting error like read-data: invalid plot file format Checking existing force monitor file cd-history... Error: read-data: invalid plot file format Error Object: *eof* can u pls help. why iam getting those error Thank u |

the problem may be on data files you want to write.
Check path, permissions, etc....
