Some problems with HuntCrossleyForce
Posted: Wed Jun 22, 2011 9:18 pm
Hi All,
I am trying to use "Hunt Crossley Force" to model foot-ground contact. I added this to my osim file, within my forceset tag:
<ForceSet name="">
<objects>
...
<HuntCrossleyForce name = "PLEASE">
<isDisabled> False </isDisabled>
<contact_parameters>
<geometry>
<objects> ground pelvis </objects>
<groups></groups>
</geometry>
<stiffness> 10 </stiffness>
<dissipation> 10 </dissipation>
<static_friction> 10 </static_friction>
<dynamic_friction> 10 </dynamic_friction>
<viscous_friction> 10 </viscous_friction>
</contact_parameters>
<transition_velocity> 0.01 </transition_velocity>
</HuntCrossleyForce>
...
When I open the osim file in GUI, It shows the contact force, but it does not show any of the parameters (I can see two folders in GUI named objects and groups but they are empty).
Does anybody know what should I do?
Cheers,
Sina
