Figure 4: Vertical data sharing in two consecutive meshes of the   -adaptive analysis of a gravity dam. The data structure relates the stiffness matrices of internal elements (yellow) to that of the reference element. The calculations for boundary element colored in blue are reused. Element matrices in the finest mesh are only evaluated for white elements.
