is there a way to reduce memory usage without reducing number of elements

YL 2020-09-30

I know it sounds silly. But I still try to ask, maybe there is some miracle.

I have a big model with ~300k elements including ~300 C3D8P elements and ~ 200 B31 elements. The minimum memory to minimize I/O from dat file is around 90GB. My machine only has a 64GB memory. so Abaqus cannot run. I am wondering if there is a way to reduce memory usage without reducing number of elements? Thanks
