[CIG-SHORT] Time step

[Brad Aagaard]

Birendra,

The time step and total time are both specified by the user. We give the 
time step priority, because usually the user cares more about time step 
than whether the total time matches exactly. For these reasons we prefer 
the code as is to changing the size of the final time step.

Regards,
Brad
