Undergrad Civil Student: need help with simulating 2d flow past a square cylinder
 

Hey,
first post on this forum.

I'm doing a Project for which we did a wind tunnel experiment for wind forces on square cylinder, and for the boundary layer development over a flat plate. I have to do the graphical ideal flow net analysis, real flow analysis from simulation, and compare to experimantal results.

Can anyone tell me what the quickest and easiest way to build a grid for a 45mm * 45mm square cylinder in a .45m*.45m X-section wind tunnel simulation and which free software to use.

Then which free 2D Solver to use for the problem and a postprocessing software can be used to calculate Cd Drag forces and lift forces and can produces pics like the attachment

Thanks for all the help
