What solver to use for sink/source flow
 

Hi all, I am new to CFD and OpenFOAM, and was wondering which solver would be best to simulate a sink/source flow. I have been browsing around the forums (not thoroughly) and online, but could not find anything on a simple 2D sink flow. It would be good if there are any examples I could use as a basis, and then edit for my university work.

Thanks!
