[Pw_forum] A few questions about MD simulations

[Axel Kohlmeyer]

Nevertheless significant compression should be possible using some knowledge of the physics, e.g. through projecting on atomic wavefunctions. Mind you, this is a lossy compression if a minimal basis is used. I've seen pretty good compression and a decent completeness for example by projecting on an STO-6G basis for example. That was with a different coff though, but still using plane waves and DFT.

large data files are written in binary format, so there
is little to be gained from compression.
