Hello Daniel, thanks for your message.
With the link I have created rectangular cuboid and using subdivided_hyper_rectangle() I got points rectangular cuboid in as well. But I still have one question. If I want to describe a deformation when the rectangular cuboid object receives a force F , how could I control the mesh moving during the force deformation ? Should I use cell or node in the surface of rectangular cuboid to represent the displacement?I s there any function in dealII for mesh control? Thanks in advance!
