Error caused due to nstep

Main Forum

Hi,

I am testing out the full body models with some motions that i extracted from sensors.
I am able to use the sensor readings as input to models and get a proper output.
But, I need to get the same amount of output anybody readings as the input sensor readings.
For instance: if i have 50 sensor readings, then i need to get 50 muscle power output.
For this reasons, when i had 68 sensor readings, i changed the nstep = 68. But, it is throwing the following errors.
Muscle recruitment solver : solver aborted after maximum number of iterations
If i change the nstep to either 67 or 69, then i get a proper and accurate output. But, i need only 68 outputs. I have also tried changing the following.
Main.Study.InverseDynamics.Criterion.Power=2;
But, it still gives the error.
Please let me know how to get over this issue.

Regards,
Raman

Hi Raman,

This means that the model is sensitive in this exact step and for some reason is out of balance.

One way would be to increase the strength of the weak muscles that helps holding the model in balance if really needed… this is not an ideal solution but way help you move on.

Try to see this wiki page.

Best regards
Søren
