[moco-announce] Moco 1.0.0 Release

[Nick Bianco]

Hello Moco Users,


Per the recent announcement from Jen Hicks, the newest version of Moco has
been released along with OpenSim 4.2! Since Moco is now merged into the
core OpenSim codebase, we’re calling this release Moco 1.0.0. It’s been a
long wait since the last release, but the time spent unifying the Moco and
OpenSim codes will ensure long term stability for the Moco project and will
allow for faster development cycles going forward.


Thanks to those who have been active contributors to the Moco forum
<https://simtk.org/plugins/phpBB/indexPhpbb.php?group_id=1815&pluginname=phpBB>!
Even though Moco releases will now be included with OpenSim releases on the
main OpenSim SimTK page, the Moco SimTK forum will remain the main hub for
all Moco related discussion.

In this release we’ve added the component
Bhargava2004SmoothedMuscleMetabolics, a smoothed implementation of the
Bhargava et al. (2004) metabolics model designed for gradient-based
optimization (contributed by Antoine Falisse). With this component and
MocoOutputGoal, you can now include metabolic cost terms in the objective
function.

We’ve fixed two major bugs related to muscle wrapping where 1)
ModOpReplaceMusclesWithDeGrooteFregly2016 did not copy over the original
muscle’s PathWrapSet and 2) muscle wrapping wasn’t thread-safe, which
disallowed parallelization with MocoCasADiSolver. Muscle wrapping should
now work seamlessly without needing to change how you construct your models
with ModelProcessor.


As always, various other small bugs fixes and changes are included with
this release. Read about them on the blog post here
<https://opensim-org.github.io/opensim-moco-site/blog/>.

Finally, the Moco paper has been published in PLOS Computational Biology! Read
the paper here

.

Best,

-Nick
