 May 3, 2013, 05:04 Simulations Flow 3D over Flat plate #1 New Member   DANG QUOC BAO Join Date: Apr 2013 Posts: 12 Rep Power: 11 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..

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

With a very fine mesh (y+ of less than 1), you can use k-omega SST that will give you the best boundary layer solution. If you don't know much about OpenFoam, you can try http://www.sim-flow.com/# It is an "automatic" way to generate an OpenFoam case. Then you can study the files and try to understand the settings.

Would you mind can help me for install simFlow. I had done follow indtructions on website www.simFlow.com but not success because i can not run the file install after finishing dowload. (i tried many tiem but it was not run). I had check "Allow executing files as program" after double clik on file and IT NOT RUN. I wish you can help me install SimFlow for studing in University? Thanks a lot...i glad to you... Bao

Try contacting their support staff as it is a Beta and they are likely trying to figure out what goes wrong. Give them as much information as you can (i.e., your system details, the steps to reproduce your problem, and whatever logs or error messages that are appropriate).
