Cook-type cantilever problem: comparison of hexahedral (a, c) and tetrahedral (b, d) elements with bubble-based (a, b) and projection-based (c, d) stabilization. Shown is the distribution of (first row); distribution of the hydrostatic pressure p (second row) in kPa; and the distribution of the stress (third row) in kPa for the fully incompressible formulation
