Hi SIMULIA community

i have to assemble two I- section shell element by using gusset plate. so modeled shell element by considering thickness and also assemble all these elements by considering thickness. but while assigning interaction properties there is a gap as selection of middle shell element part. so its fine to continue this or modeled again is such a way that all shall elements contact each other (but while tick render shell thickness function they seems to be intersect).

I also attached image for batter clearance of my doubt.

Thank you for your support
