mended. Check which is the average temperature via a
few steps of a microcanonical simulation. Don't increase the temperature
too much. Finally switch on the thermostat. In the case of molecular system,
different modes have to be thermalized: it is better to use a chain of 
thermostat or equivalently running different simulations with different 
frequencies.
