The model is meshed mostly with the higher-order hexahedral SOLID186 elements (about 99.4 percent of the total mesh), as shown in the following figure. However, it also has relatively a small number of tetrahedral SOLID187 elements (about 0.6 percent of the total mesh).

Figure 62.3: Mesh of the Abdominal Aorta Model

The mesh consists of 62123 elements with 4 elements to represent the wall thickness and at least 52 elements (or more) in the circumferential direction at most locations. Mixed u-P element formulation is enabled (KEYOPT(6) = 1).
