Narrow channel - fluid bearing

Hello,

I'm using solidworks flow simulation to solve the fluid field in a submerged journal bearing (between two uncocentric cylinders), very similar to this:http://ars.els-cdn.com/content/image/1-s2.0-S0301679X01000226-gr1.gif

I have some problems solving this case because and getting enough fluid cells and when i do, the simulation lack in memory and crash.

Which of the initial mesh/mesh settings should I change in order to find the best combination between results (enough fluid cells) and memory ?

I hope I'll find a way to solve this without using a server or a computer with bigger memory.

The part is attached if anyone wants to try for himself

Thank you
