[DFTB-Plus-User] Energy Conservation for MD in dftb+

[gxaaas]

Hi all, 
    When I test the MD in dftb+ for system of about 2000 atoms with 'SCCTolerance = 1.0E-005', 'TimeStep = 0.5 fs', the final total MD energy oscillate around 150meV.   Could someone give comments on this point, should the range be smaller for general MD simulation?
Thanks!
