檢視 $LowTmode 的原始碼

$LowTmode  is a special function aiming at solving the low-temperature problem. At low temperatures, due to the exp(E/kBT) issues, the program is easy to get NAN during iteration with bad initial guess ( it should be right at convergence condition). Hence, this function assumes that the potential profile is similar at high T and low T. It solves high T first and use this solution for the low T's initial guess. 

 Usage:

 $opertemp
 10.0
 
 $LowTmode
 300.00 0.4   

 The program should run for 10K. But it will run 300K first. 
 Then run 300.0 * 0.4 =120K 
 Then run 120.0 * 0.4 =48K 
 Then run 48.0  * 0.4 =19.2K 
 Then run 19.2 * 0.4 = 7.68 K -> force to be 10K
