I dont kow how you geometry looks exactly but you can try the follwoing journal file in gambit (file->run journal).
It creates a rectangle, inserts a sheet and meshes it with a fixed sizing function.


/ Journal File for GAMBIT 2.2.30, Database 2.2.14, ntx86
face create width 10 height 10 xyplane rectangle
vertex create coordinates 0 0 0
vertex move "vertex.5" offset -2 0 0
vertex cmove "vertex.5" multiple 1 offset 4 0 0
edge create straight "vertex.5" "vertex.6"
face split "face.1" virtual edges "edge.5" tolerance 1e-05
sfunction create sourceedges "edge.5" startsize 0.1 growthrate 1.2 sizelimit \
1 attachfaces "v_face.2" fixed
sfunction bgrid attachfaces "v_face.2"
face mesh "v_face.2" triangle
window matrix 1 entries 1 0 0 0 0 1 0 0 0 0 1 0 -6.504730224609 \

Good Luck

I doing same as u said but there is an error like Can't split face.1 with edge edge.5 whose end vertices are not on face boundary.
