convergence speed

In some previous FEA software I looked at, there was an option to limit the degrees of freedom to speed up solution times. In a 3D model for example, one could only look at movement along the y axis, ignoring the x and z. I am wondering if there is a way to do this in COMSOL, and if so, would it be useful to increase convergence speed?
On a related note, are there any ideas on what convergence speed should I expect from a 3D model of laminar flow interacting with a solid, very simple geometry, on 8GIG 64 bit Windows 7? I realize it's hard to say, but some of my models have been running for days, so I'm wondering if I should expect convergence in days or in hours?
Thanks,
Anton
