I am trying to do a coupled field analysis, FLUID-Structure interaction. Wind strikes normally a panel covered by a very thin and flexible material that is polyethylene film and displacement of the film is what i need. The analysis is 2D. I create the flotran environment but when it comes to the structural one i am a little bit confused. That is because I am trying to find the proper 2D element for the film area that must have DOFs UX,UY AND ROTZ... that is because the film is both sided pinned (the need for rotz). I can solve the problem by using plane or solid elements no 2D element of this kind has rotational (rotz) degree of freedom. Shell elements do but i am a little bit confused with the thickness that is demanded (i need x direction to be ny thickness) ...what is the proper element to use?
