Overcoming Barriers to using SimTk: Solutions and Advantages for Biomechanics

Explore the barriers and solutions to utilizing SimTk in biomechanics research, including issues of pride, support, legacy code, learning curve, and trust. Discover the advantages of using SimTk, such as access to tools, teaching materials, improved productivity, and source code availability. Additionally, learn how to overcome barriers to contributing to SimTk and the benefits of doing so.

  1. Group 1 Barriers for SimTk

  2. Barriers to using SimTk

  3. Barriers to use of SimTk1. “not invented here” • Lost productivity • Pride (my tools are better) Solutions: • Payoff should be clear • Darwinism • Community: students can find support

  4. Barriers to use of SimTk2. Don’t know about it Solutions: • Publicity and advertising by Simbios center

  5. Barriers to use of SimTk3. Support/continuity Solutions: • “too big to die” • Someone gets paid to provide support • Grow user group (and its competence) by training • Compare to SD/Fast: not well supported, continuity uncertain

  6. Barriers to use of SimTk4. Use of legacy models and code Solutions: SimTk plans to provide file translators and code emulators (e.g. SD/Fast)

  7. Barriers to use of SimTk5. Too hard to learn Solutions: • Training: course materials and courses at Simbios • Some end user applications (OpenSim)

  8. Barriers to use of SimTk6. Students prefer Matlab Solutions: • SimTk will provide Matlab MEX file wrappers (and python, Java, etc)

  9. Barriers to use of SimTk7. I will have to share my work This is a misunderstanding: you can use SimTk without contributing.

  10. Barriers to use of SimTk8. Can I trust the tools? Solutions: • Build reputation, large user base • Peer review (like Amazon) • SimTk provides demo simulations

  11. Advantages for using SimTk

  12. Advantages for use of SimTk • Access to tools developed by others • Never call PTC again to pay or get support • Access to teaching materials • Productivity • Access to source code

  13. Barriers to contributing to SimTk

  14. Barriers to contributing1. “freeloading” Solutions: • Remember: you can’t get rich in biomechanics • You can limit your contributions to non-commercial use

  15. Barriers to contributing2. Will I get academic credit? (it takes time to prepare a contribution to SimTk) (loss of identity, will work be seen as Stanford?) Solutions: • Showcase your work to get more publications • You can limit your contributions to non-commercial use • Put your logo on your SimTk project etc.

  16. Barriers to contributing3. Will I lose my competitive edge? Solutions: • You decide what to share, when, and with whom

  17. Barriers to contributing4. Overhead to be SimTk compliant Solutions: • It has advantages too

  18. Advantages to contributing

  19. Advantages to contributing • Doing good, “karma” • Showing off • Portability/independence/continuity • Having a community • Not reinventing the wheel • Hosting service, source code control • Forces students to leave legacy with documentation, good practices • Satisfy NIH dissemination requirements
