Special methods were used to mesh elements bolt type, method "Sweep"<br />
automatically controls the direction of formation of elements from source to<br />
target, complicated areas, narrow and difficult and discretized mesh of<br />
tetrahedra. For cartilage and menisci have used items such as bolt and the<br />
femur, tibia, fibula or used with node tetrahedral elements in the middle.<br />
Fig.3 – Support "Remote Displacement" model that allows rotation<br />
of the head of the tibia and fibula after distal axis Y.<br />

For efficient discretization for this analysis we used elements of size 1 or<br />
1.5 mm for areas of greatest interest, the possible transition (transition) from<br />
this to a larger size through options "Smoothing" the environment and<br />
"Transition" on fast, for each component added a dimension element "element<br />
size", obviously a smaller contact areas tibio-femoral, and greater the jamb. For
