Hi all
I am new to GAMBIT and FLUENT
I created vertices by using this journal code:
$i = 0
$imax = 5
$inc = 0.0001
do para "$i" init 0 cond ($i .le. $imax) incr $inc
vertex create coordinate $i (SQRT($i)) 0
enddo
this code creates vertices of the y=sqrt(x) function (create 15974 vertices!!!)
So, now I want to create an edge by fitting a smooth curve between all of these vertices( the most appropriate edge form these vertices).
What is the most appropriate edge type for the best accuracy??

I tried to create edge with NURBS edge, first I selected all vertices and then I clicked on Apply, but when I zoom on the edge it seems that edge didn't pass between all vertices (the edge has a little distance from the vertices except the first one and the last)!!!!
Why??
NURBS edge is useful for this case, isn't it??
what is my fault?
