details. Users can further understand the solution behaviors by
modifying the boundary conditions.
With the imported CAD model, a finite element mesh
is generated as shown in the figure. The mesh consists of 5,221
tetrahedral elements and 9,881 nodes. Since there are three
,
displacement unknowns of ,u v w at each node, the problem thus
contains the total of 29,643 equations before applying the boundary
conditions.
The model is constraint as fixed support at the two
holes as shown by the symbol A in the figure. An offset loading is
applied at the other end as indicated by the symbol B.
