I solved very simple problem: laminar cylinder (Re=20) in flow using OpenFOAM 2.1.1.
I used blockMesh instrument. (number of cells: 78000)
The cylinder is divided into 8 parts.
I received Cd which coincides with experiment.
Today I run the same problem on OpenFOAM 2.2.0.
The Cd is approximately 4 times smaller. It differs from my previous calculations and from experiment.
I suppose that something have change in the rules concerning forceCoeffs.
But I did not find answer in 2.2.0 manual.
Please help me!
Thank you very much in advance.
