Results

When the analysis is completed, the results can be viewed by opening the analysis file *.avz in AquaView. Figure 10 shows the vertical position of the tank model when selecting Results > Location > Position Z [m].

Figure 11 shows the relative pressure at the center of each element. The pressure is evaluated at the element midpoint and color-mapped accordingly. Note that pressure from the outside is taken as positive, meaning the internal hydrostatic pressure acting outward on the tank wall is shown as negative relative pressure. As expected, the results correspond well with the theoretical hydrostatic distribution where pressure increases linearly with depth.

As seen from Figure 11 results correspond with location. Figure 12 shows the Von Mises stress distribution in the tank elements.
