Hello @ptrblck, thank you for your response. As I said, I understand how to rotate the tensor as a whole and how to rotate individual [x, y] displacement components inside of the tensor.
My question was whether there was a way to do that rotation on all elements of the tensor at once in an efficient way. As of now, what I have are operations that have to be applied to every displacement element of the tensor space-wise, but I suspect there might be a better way to do it on the entire tensor with a single matrix multiplication. I was trying to tap into some brainpower here to help me with figuring out how to implement that, or at least, what that could look like.
