How to mesh Aluminum Honeycomb having foil thickness 150 microns for drop test simulation.

I want to design impact attenuator for that i have modeled a aluminum honeycomb structure. Now i am doing drop test simulation but while meshing the model sometime i got system memory low error or sometime error related to mesh size. I also kept element size below 150 microns, very fine meshing, but after waiting so long i got the same error.
