| * Craig did not have a chance to explore hexahedral meshing workflows in Salome for STL surfaces. * Craig focused his attention on documenting his findings on the convergence of Open Knee(s) - Generation 1 model when using springs to stabilize menisci. The group went over the wiki page to evalaute Craig's findings. Craig simulated passive flexion up to 90 degrees in 1 s. Model without any springs converged up to 12 degrees of flexion. It seemed like stabilization of the menisci helped convergence. This indicates that convergence issues of related to Open Knee(s) - Generation 1 may be due to free floating behavior of the menisci. Ahmet noted that previously, during slower flexion rate, the simulations have completed to 45 degrees (in 1 s) without the springs. He asked Craig to conduct simulations without springs up to 45 degrees flexion (in 1 s), then up to 90 degrees flexion (in 2 s) and in following conduct the simulations with springs again. * Craig incorporated text from his abstract to the anatomical imaging. Ahmet asked him to also prepare a list of paragraphs, figures, and tables to outline a detailed draft. |

- Robb
- Perform and upload left knee coordinate system versions for oks003, of combined loading data for tibiofemoral joint at 90 degree flexion.
- Perform and upload post-experiment calibration file for contact pressure data of oks007.
- Prepare detailed list of paragraphs and figures and tables for imaging data manuscript.
- Tara
- Upload oks008 tibiofemoral joint testing data to data management site.
- Complete detailed list of paragraphs and figures and tables for imaging data manuscript.
Ongoing Action Items:
- Craig
- Anatomical imaging manuscript.
- Large-scale analysis of simulation parameters for convergence.
- Snehal
- Pivot shift manuscript.
Cruciate ligament modeling & simulation.
- Robb
- Patellofemoral joint experimentation manuscript.
- Tara
- Tibiofemoral joint experimentation manuscript.
Notes:
- Discuss immediate action items from the last meeting.
- Ahmet tried to disseminate joint mechanics data for oks003 and oks008. He identified a couple folders in the tibiofemoral joint testing data of oks003 where the measurements were not processed and converted to the physical left knee coordinate systems. Robb will fix this issue. When Ahmet tried to work on the dissemination of oks008, he realized that the zip file for the tibiofemoral joint testing, which was previously uploaded to the in house data management system, was empty. Tara will upload raw tibiofemoral joint testing data for oks003 again for further organization and dissemination. Ahmet has not worked on oks004 yet. oks007 still misses a post-experiment calibration of pressure sensor to complete the patellofemoral joint testing data. Robb will provide this.
- Ahmet still has to prepare flowcharts to describe data flow for pre-processing of joint kinematics/kinetics data.
- Ahmet contacted the Advisory Board to schedule a meeting during November 2015. He will follow up.
- Craig did not have a chance to explore hexahedral meshing workflows in Salome for STL surfaces.
- Craig focused his attention on documenting his findings on the convergence of Open Knee(s) - Generation 1 model when using springs to stabilize menisci. The group went over the wiki page to evalaute Craig's findings. Craig simulated passive flexion up to 90 degrees in 1 s. Model without any springs converged up to 12 degrees of flexion. It seemed like stabilization of the menisci helped convergence. This indicates that convergence issues of related to Open Knee(s) - Generation 1 may be due to free floating behavior of the menisci. Ahmet noted that previously, during slower flexion rate, the simulations have completed to 45 degrees (in 1 s) without the springs. He asked Craig to conduct simulations without springs up to 45 degrees flexion (in 1 s), then up to 90 degrees flexion (in 2 s) and in following conduct the simulations with springs again.
