You really need to update, R18 is a long way behing the current solver. 

Depending on models 24GB will allow 6-8M cells, possibly nearer 12-18M with SIMPLE but adding in VOF is likely to push you to the lower end. It also depends on the element types. Modelling more complex shapes will need more cells, so you'll need to see if you can take advantage of symmetry or use a bigger computer.
