Default very low drag
Posts: n/a
dear friends,

i am solving a laminar unsteady flow across a square cylinder which is confined by walls on both sides. ths side of the square cylinder is 10 cm. i exported the mesh to fluent and scaled it to metres.i hav etaken air as my fluid. my reynold no. is 100 and the velocity at that reynold no. is 0.146 m/s. formulation used is implicit. solver used is segregated. problem is that i am getting a very low value of drag..about 0.0003. the correct value is about 1.4.. i could not find where i went wrong. can u help me

thanks a lot

You may want to be careful in the unit conversion. I suggest you model in Gambit using metres and also make sure your ref. values are correct.
