Our thermal conductivity calculations also show that scaling method results |
| 426 |
< |
agree with swapping method. Table \ref{thermal} lists our simulation |
| 427 |
< |
results with similar manner we used in shear viscosity |
| 428 |
< |
calculation. All the data reported from scaling method were obtained |
| 429 |
< |
by simulations of 10-step exchange frequency, and the target exchange |
| 430 |
< |
kinetic energy were set to produce equivalent kinetic energy flux as |
| 431 |
< |
in swapping method. Figure \ref{thermalGrad} exhibits similar thermal |
| 432 |
< |
gradients of respective similar kinetic energy flux. |

tested (Table \ref{thermalLJRes}) using swapping method. With a fixed |

similar thermal gradients were observed with similar thermal flux in |

two simulation methods (Figure \ref{thermalGrad}). |
