speeding up the calculation / iteration in fluent
 

Hi sorry take your time.
is there a way, speeding up the calculation / iteration in fluent? (is it effective to minimize mesh with scale_mesh? or must upgrade specs of hardware? or make the mesh be coarse? or is there another ways?)

*I'm making a simple 3D flow simulation. The flow of water from duct fill the tub. the geometry is not large, about 1mx0.45mx0.45m, but it must make me wait until the results iterasiny time -+ 12 hours with a "time step" produced just 4 seconds and tub is 10% of full.

and if I make the time as I want until the tank is full, I do not know how much longer to wait. may be, days

please, i need your suggest, dear friends

ps: my Notebook specs is not bad, Memory 4Gb, VGA Nvidia 2Gb, Core i-3
