Thank you for your quick answer, excuse me but I have another question
about the photographs that we send you yesterday.
We have a problem, when we obtain the photographs; during the movement
we have some pictures where the growth of the muscular mass changes
quickly.
This change isn’t normal because in the previous and the subsequent
photographs, the muscle mass is equal.
Could you tell us if this is only an interface problem or it’s another
problem?
I have looked at the pictures and it looks like the model is
overloaded at certain parts of the analysis? and there are also
fluctuations in the activities which causes the muscles to bulge up
and down between the timesteps.
This can be caused by many things, for example fluctuations in
accelerations if the magnitude of the accelerations is significant,
you can check this by looking at the accelrations of for example the
hand segment.
It can also be inssuficient or unrealistic boundary conditions to the
model. You will get strange results for example if the model is about
to loose its balance, i do not recall exactly how your model is
supported by the environment?
If you add a small linear penalty in your Study folder it may also
help prevent fluctuations in the activity. The property is named
RecruitmentLpPenalty, a value of lets say 0.00001 might help reduce
the fluctuations. You can read the full explanation of this property
in the ref manual, but in short it adds a linear penalty to any
muscle activity in the model not just the max one. This sometimes
help prevent fluctuations.
If you would like to switch off the muscle bulging dependent on
actitivity, this can be done in the DrawSettings file, by setting the
property Muscle.Bulging to zero.
I hope this helps you move on, otherwise please write again.
Best regards
Søren, AnyBody support
