Dear ALL,
 
Recently, I have faced the maximumcurrent flows warning. Do anyone know what actual the main cause?
 
I suspect is the R package/ R _pin value that is too small. I try to replace some larger value
and simulate again. I found that the problems gone. Is it that mean the problem cause by the R?
 
Below are the message the shown after use ibischk3.
