Hello,


A bug was found. In the xtp tutorials of KMC, 1000 seconds of KMC simulation 
was scheduled to run. However, after checking the output, I found that only 
1000 steps of KMC was executed. According to the manual, if 'runtime' is larger 
than 100, it may be steps.


What's more, another issue relating to KMC made me a bit nervous. I want to 
operate a kmc simulation to calculate charge mobility. I made this calculation 
with the calculator kmcmultiple. From the article [1], two methods can be 
applied to calculate the mobility. One is with the Einstein relationship, and 
another one is with the equation μ=μE/E (as shown in the following figure).



However, during the calculation, I changed the strength of electric field, but 
μE dosen't change a little. And I have no idea on how to calculate this with 
Einstein relationship for I found that only overall mobility was ouputed but 
the mobility of every direction cannot be found.


Sorry to disturb you! Thx a lot!




Best regards,

Hengyue Zhang
