How to fill gaps between surfaces after making mid-surface operation ?

AHMET_21209

Hi Everyone,

I have a 3-D truss structure to make bending analysis. So, I converted the analysis 3D to 2D by making a mid-surface operation. 

But when I use mid-surface for box-section profiles, gaps showed up between surfaces, naturally. 

I would like to ask how I can eliminate the gaps between surfaces? and should I do this editing with surface edit commands or mesh edit commands after meshing operation? 

You can see the red lines in the below figures.

you might want to try the 'surface edit' >> extend tool

 

try picking all your surfs and adjust the maximum distance/tolerance.

This might help you to get all of them connected.
