Hello all friends, i want use size function, i tried size function it is not work properly. I make a box and inside that a sheet is inserted and i apply size function on sheet but it not work proprly. it make only half side not cover the full sheet. it cover only half side. please give ans.

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.

If your gemoetrie looks like this we can discuss further.

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.
