Drop Test causing SolidWorks to crash.

I am doing a drop test study for an assembly containing several components of a wheelchair. I seem to be low on memory (My PC has 8 GB RAM and an i7 processor), as SW often crashes during either the meshing or when I run the study. I've tried using shell strategies, but it appears shell elements aren't supported in drop test. I've also followed an SW document on optimizing SW and Windows settings to increase performance. Could I have some advice as to what else I could do to help my drop test run?
