RAM and hyperelastic

Hi,

I have just run an interesting hyperelastic model, it took 3 days and did not complete. (I can't share the model).

Over the 3 days I periodically monitored the study and watched the RAM get gradually used up (including virtual disk)

eventually it ate the complete 48Gb actual and lots of virtual and completed with a fatal error at step 150 of 201 on pass 2.

Fortunately the info I required happens at about step 140.

Any thoughts?
