Femur and tibia fixed coordinate systems - Connectors¶
Connectors are placed on the fixed femur and tibia coordinate systems. These connectors can be used to apply loads or boundary conditions to the femur/tibia’s fixed coordinate system.
Nodes¶
Connector elements are defined to be coincident with the axes of the femur and tibia fixed coordinate systems. Nodes are placed on each axis (6 total) and the origin of both coordinate systems is already defined.
Elements¶
A total of six elements are defined between the femur and tibia fixed coordinate systems. On each coordinate system, three elements are defined using the node that is defined at the origin, and the nodes that lie on each of the axes.
Ties¶
All of the nodes that lie on the femur’s fixed coordinate system are rigidly tied to the femur’s bone geometry. Similarly, all of the nodes that are on the tibia’s fixed coordinate system are rigidly tied to the tibia’s bone geometry.
