3. Results<br />
Control conditions of the analysis are:<br />
i) the analysis was run in a time of 1 s;<br />
ii) is now nonlinear and large number of nodes and elements is necessary<br />
to implement a system subsets analysis: subset 10, the initial step: 5 step up:<br />
100.<br />
iii) type iterative solver is: PCG level 2.<br />
Fig. 1 – Virtual 3D Model of the complex human knee joint (left) and tibia, meniscus<br />
and cartilage of the proximal head of the tibia in the right image.<br />
Fig. 2 – Force applied and the degrees of freedom assigned<br />
geometrical model for analysis.<br />
Boundary conditions for this analysis are:<br />
i) the red is observed positioning of the femoral bone in the centre of the<br />
sphere, the area where force is applied evenly distribute of 800N, direction-Z;<br />
ii) the yellow picture above to see a drop in the same location, but in that<br />
area is allowed by the Y-axis rotation system, the remaining displacement after<br />
X, Y, respectively rotations x, z are 0;<br />
iii) in the picture below it can be seen through the media type: Remote<br />
Displacement, support which allows movement of the ankle by letting free the<br />
rotation direction Y.<br />
Mesh nodes and elements in the geometric model was made with bolttype<br />
items such as solid type tetrahedral Solid186 and Solid187, both with the<br />
middle nodes; that are required for a better approximation of the results and<br />
their accuracy.
