Hope this finds you well... i am having a problem analyzing a simple model that consists of 2 rectangles intersecting. the creation of the rectangles, material definition, BC, loading conditions...etc is done. but first: how can i define one rectangle to be a rigid body? second: the vertical rectangle seem to deform, but has no effect whatsoever on the horizontal rectangle?? Please help. Thank you in advance P.S i've included a file of the model.
