Hi, I am now revisiting some work concerning plate bending where the 2D planar elements can exist in 3D space. This typically requires gradients of solution variables in the plane of the element, which is then mapped to the global coordinate space. In the past, I have created a local xyzcoordinate system for each element, and then created a new element for computations that lies in an xyplane. Then, the matrices and vectors are transformed to the global xyzcoordinate before assembly. I am curious if there is are any procedures within libMesh to account for such cases of 2D planar elements in 3D spaces. Ofcourse, the procedure I define above would not apply to curved elements and a more refined method using tensors would perhaps be needed. I would appreciate any inputs. Thanks, Manav
