Static optimization crash

Post by Carlos Ramirez » Fri Aug 01, 2014 1:56 pm

Hello, i have got IK of lower extremities with a custom model based on 3DGaitModel2354 , and i would like to do static optimization on this movement, but when i click run on this tool, opensim closes, what do i have to check, i mean log file or something to realize what is the problem and how to complete the static optimization step.
Thank you in advance.

I have found the log file´s error when i try to do the static optimization step.
Here it is. May be somebody would like to check what could be wrong.
Thank you

Carlos

A few days ago I believe you had your model uploaded. I downloaded it and played around a little bit. I believe if you change your thorax joint to a weld joint that it will work.

<Body name="thorax">
<mass>15.6903353239452</mass>
<mass_center> -0.12797 -0.13354 0.0115064</mass_center>
<inertia_xx>0.270280513098911</inertia_xx>
<inertia_yy>0.123967353014763</inertia_yy>
<inertia_zz>0.218867763026006</inertia_zz>
<inertia_xy>0.02441147645256</inertia_xy>
<inertia_xz>-0.008948253626665</inertia_xz>
<inertia_yz>-0.003326809054344</inertia_yz>
<!--Joint that connects this body with the parent body.-->
<Joint>
<WeldJoint name="ground_thorax">
<parent_body> ground </parent_body>
<location_in_parent> 0.000000000000 0.000000000000 0.000000000000 </location_in_parent>
<orientation_in_parent> 0.000000000000 0.000000000000 0.000000000000 </orientation_in_parent>
<location> 0.000000000000 0.000000000000 0.000000000000 </location>
<orientation> 0.000000000000 0.000000000000 0.000000000000 </orientation>
</WeldJoint>
</Joint>

Running it with a few of my own kinematics files from a similar model gave exceptional results and actually helped to fix a problem of my own. Thank you!!

I have the same error you describe.
Did you find a solution?

Gabriel,
Could you explain why changing the thorax joint to a weld will enable the static optimization? Just curious as I am learning more about the program. Thanks,
Julie
