I like Code_Saturne. It has a GUI that greatly simplifies the whole process. You can use SALOME to make the initial model and then mesh it, and also use it to visualize the results. All of these programs come precompiled on a live Linux distro called CAElinux.

In any case, check out CAElinux. It's going to be the least hassle out of any of your choices because everything comes precompiled.
