[Gambit] I have touble in grading.
 
Hi :confused:
I'm a first step in Fluent and gambit.

I'm using [Gambit2.1.x:trainging Notes] to learn a gambit.

But at the first step I could not understand about grading(dividing edge).

In a book, grading has 8 option (succesive ratio,first length, last lenth,
first last ratio,last first ratio, exponent, bi-exponent , bell shaped)

but I just understand only succesive ratio.....

please help me to understand rest of dividing option.

and please recommend another good training book about gambit.

my manual has a few explanation.

thank you

grading isn't dividing.
what you are talking about, is node distribution along one edge.
successive ratio is the default one: node distribution is constant (no grading)
Regarding the other I am only using exponent and bi-exponent ("heavy" node distribution at one extremity or both extremities (bi-exponent)
