[esp-r] Time steps

[wakana-m at ec.hokudai.ac.jp]

Dear all,

 Hello.
 I'm a graduate student in Japan.
 I want to know how to simulate on a second basis.

 Until now, I've simulated on a minute basis.
 I've input "60/1" in the initiate simulation window.
 Now I try to simulate on a second basis.
 However the input value for 'time-steps/hour' should be less than 60. 
 Thus, how can I do if I want to simulate the model by seconds ?

 Any advice would be appreciated.

 Regards,

 Wakana Matsumoto
