System requirements to run COMSOL simulations involving millions of degrees of freedom

Hello,
I want to run transient comsol simulations that involve ~10 million degrees of freedom on a workstation equipped with a new Intel Xeon processor (3.06GHz speed). From your experience, how much RAM is required to run effectively such a simulation and is this feasible as far as the solution time is concern? If it is not feasible what are the system requirements that will allow me to run these simulations?
I use both COMSOL 4.2 and 3.5a. Is the new version faster in solving large simulations than the older one?
thank you very much,
Fyllos

Hi
I run about 2-3 MDof on 48Gb, depends quite a bit on your model and solver, so you would need quite some RAM ;)
In anycase use the latest version, in my opinion

Good luck

See this www.comsol.com/community/forums/general/thread/863/
It says that to run a problem with a million DOF, you need about 20GB for a direct solver.
