View Full Version : Contact force in LSDYNA

09-18-2005, 03:47 PM
Dear colleagues;

We are using ANSYS-LSDYNA to conduct a simulation of total knee
replacement mechanics during flexion. We plan to verify our finite
element analysis against our experimental data which measured the contact
(compression) force of the femoral component on the polyethylene inlay
during flexion. However there is some difficulty in obtaining data for
this force from the Time-History PostProcessor in LSDYNA. Both
components are meshed with SHELL-163 (rigid) elements. Does anyone have
experience in this matter?

Best regards,
- Rochelle Nicholls
