Hi all,
I am new user using OpenFoam,. I am making simulation flow steady over the flat plate 3D with dim ( c =0.2 m and l=0.7 m). What solver can i use for solving this proplem. I had tried many time but had many errors. I want to calculate the lift, drag cofficient on the flat plate but i don't know how do it? I wish i have help me for solving this proplem from all members of CFD online.
Thank you so much..

Hi,

For the steady simulations of incompressible, turbulent flow, you can use simpleFoam solver.
For the steady simulations of compressible, turbulent flow, you can use rhoSimpleFoam solver.

You can use the forceCoeffs function object to calculate the force coefficients.
and find the information about how to use it by doing the motorBike tutorial.

Best regards,
Fumiya

Dear Fumiya
I had done this proplem along your intructions and had result Cm 8.27999e-05 Cd 0.000173674 Cl 0.00082136. Conditions of Promblem: velocity inlet 1 m/s, nutida 0.001 at inlet and Zerogradient at other boundary, pressure equal 0 at outlet and ZeroGradient at outlet. At wall (flat plate) fix value
(0,0,0) velocity and Pressure is zeroGradient. Dimmentions of flat plate (0.4mx1mX0.01m). Model mesh 220.000 point.
I dont have much experience in CFD Calculations, I don't know that is Result is good or bad ? I dont know edit where part of problem for having good result?
Would you mind help solve this proplem? I am do my thesis for graduate university. With project "Simulation flow over Propeller". very difficult.
I wish i have your help.
Thank you very much.
