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 xyz-coordinate system for each
element, and then created a new element for computations that lies in an
xy-plane. Then, the matrices and vectors are transformed to the global
xyz-coordinate 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
