Case  1: coarse mesh (total element number: 6008) subjected to uniform pressure loading.
Case  2: finer mesh (total element: 24032) subjected to uniform pressure loading.
Case  3: coarse mesh (total element number: 6008) subjected to local loading.
Case  4: finer mesh (total element: 24032) subjected to local loading.
