nI figured out that I have some unattached geometry. My main geometry is to plates perpendicular to one another to form a stiffened plate. (one plate acts as a beam, but because of limitations I've modeled it as a plate to consider the geometrical imperfections using equation tool in Spaceclaim)nI must say that I've used share topology option in Spaceclaim, but still its unattached, It would be nice if you could give me some advice on that.nn
