Dear Friends, The stress-wave propagation speed is calculated using : sqrt (elastic modulus/density) The unit of elastic modulus is GPa, and that of density is gram/cm^dim Can anyone please tell me how I can convert the resulting value to m/s (meter/second)? Regards

thanks for your help. 1) That is enthalpy when the solid melts. 2) 4530 ev is for 27000 atoms.

Thank you for your respone. I calculated it. Is that correct? number of atoms = 27000 silicon mass = 28.0855*1.66054*10^-27 Kg 1 Kg silicon = 35.6 mole (4530*1.6*10^-19)/(27000*28.0855*1.66054*10^-27 ) = 600 KJ/Kg 600/35.6 = 16.85 KJ/mole

Dear Friends, Could you tell me how I can convert electronvolt to joule/mole for silicon material? I want to convert 4530 ev to joule/mole for silicon. Many thanks in advance.

Dear Friends, I'm trying to bulid a non-ideal hcp lattice in order to use in MD simualtion. I have12 lattice basis. but 2 of them are negative values. Can anyone tell me how I can convert the negative values to positive? 0.66667 0.33333 -0.0416 0.66667 0.33333 -0.1668
