Hello all, I'm working on model editing tutorial (arm_with_bucket.osim). I have followed all the steps in the tutorial but couldn't open this file in GUI. It takes very long time to load this file. I couldn't decipher anything from the log files and they are attached here (err.log file is empty). Pl...

Hello all, I have switched to OpenSim 3.3 and I could not longer see the experimental and virtual markers together, when I preview the markers after scaling. How do you think I can see both the marker sets at a time? In my process of iterating scaling, I match up my virtual marker to the experimenta...

Hello all, I did read about Pelvic Tilt and Hip Flexion Angle (Gait2354 vs. Clinical Measurements) on opensim confluence. Q1. I have simulated squat in opensim and couldn’t match the hip flexion angles to the literature, though I got decent knee flexion and ankle angles. This has further effected my...

You are Welcome Bruce! Try to alter the weights on the markers while you run your IK to get the max marker error below 4cm and rms below 2cm. You may try to uncheck the markers (to give a default weight of zero) which you are not confident of, to reduce the error. Opensim doesn't filter the force da...

yeah! I have set the gravity to 0 with in the model.

Hello Bruce de Jongh, I wanted to make sure if you are simulating gait motion and running the simulation just for stance. I have got the residuals reported above for a badly scaled model, which I have later modified to recommended values of Opensim. So, make sure the maximum and rms marker error dur...

Hello all, I’m trying to simulate squat in Zero gravity to understand Muscle forces and Joint reactions. I want to apply constant force at the shoulders of the Model during the activity. Since I’m performing simulations in zero gravity, without a constraint my model keeps falling down (while running...

Dear Opensim team,

We could not view or download attachments on Public forums. It opens a new tab saying "The selected attachment doesn't exist anymore". Can you please let us know how to access them? Thank You

Hello all,

Opensim crashed while I'm using analyze tool after finishing 60% of the simulation. I did test it with debug 3 mode to look up for feedback during the run (it dint help). You may look at the error log report attached. Any suggestions in this regard are golden.

Thank You
Satya
