Barriers for SimTk

2. Barriers to using SimTk

3. Barriers to use of SimTk 1. “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 SimTk 2. Don’t know about it
Solutions:
Publicity and advertising by Simbios center

5. Barriers to use of SimTk 3. 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 SimTk 4. 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 SimTk 5. Too hard to learn
Solutions:
Training: course materials and courses at Simbios
Some end user applications (OpenSim)

8. Barriers to use of SimTk 6. Students prefer Matlab
Solutions:
SimTk will provide Matlab MEX file wrappers (and python, Java, etc)

9. Barriers to use of SimTk 7. I will have to share my work
This is a misunderstanding: you can use SimTk without contributing.

10. Barriers to use of SimTk 8. 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 contributing 1. “freeloading”
Solutions:
Remember: you can’t get rich in biomechanics
You can limit your contributions to non-commercial use

15. Barriers to contributing 2. 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 contributing 3. Will I lose my competitive edge?
Solutions:
You decide what to share, when, and with whom

17. Barriers to contributing 4. 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
