I am sorry for such a basic question, but I have searched and I cannot find an answer.
I just want to fill this area and I believe grid fill is what I would want to keep the curvature of the model when filling in the hole. However, the selection does not satisfy the requirements of grid fill.
Is there any other operator I could use to fill the hole while keeping the curvature of the model? Or can I somehow make grid fill work?
