Dear all,

I know that CFD is a powerful tool to simulate any physical problem. I want to draw stream lines around spheres that are placed equally spaced into a incompresible laminar fluid. Also I want to evaluate the velocity component at any locations? Could you please suggest me free CFD software or very low cost? I'm really appreciate your help...thanks.

I have heard of a software called FlowSim 2d that may be of some help. I will try to talk to the guy who wrote it to see if he can assist you!

if have access to a mac you can also try Quick 'n'Simple which is available at http://icemcfd.com/cfd/CFD_codes_p.html#QnS it uses the SIMPLE pressure based method and QUICK differencing and is quite easy to use

I download quick'n'simple. How can I draw spheres or circles into the grid?.

i haven't used the code in years. perhaps you can contact the author of the code
