I am currently trying to drive the latest TLEM model using the old
AnyKinEqSimpleDriver’s. I am doing this to compare kinematics and
kinetics from optimised and unoptimised models. I have constrained the
models rigid degree’s of freedom with driver sets similar to the
freeposture model, but adding new SubTalar drivers. When I try and set
the initial pos the model is failing in time step 0, with larg errors
throughout the constraints.
I have added the model under unoptimised.zip, and I am currently using
the MarkerPlacementStudy to run the model.
It seems your model has not been uploaded successfully. It is probably our
fault as the file section was running out of space. But I made some cleaning
and you should be able to upload it now, then we will look at it.

The problem is that the initial position of the model is too far from the
markers. I uploaded a new version of the JointsAndDrivers5.any with the
static drivers of the free posture model.
When you run setInitialConditions you will see that the pelvis is in a
correct position but the legs are very far from the markers. So in a first
time you have to adjust the initial position in the mannequin file the have
the body markers and free markers as close as possible. Then you have to
free one DOF at a time by removing the static driver and replace by the
corresponding linear driver between 2 markers. It is important to replace
them one by one (starting by the pelvis) and verify that the model is still
solving the initial conditions each time.
