Problem with the wrist rotation

#1

Hello everyone,

I am currently using the freeposturemove file to obtain the wrist motion.
I am only using two motion points in the mannequin.any for both wrist flexion and abduction.
The first is the initial point which is zero for both wrist flexion and abduction.
The second point is -87.0 for wrist flexion and -30.0 for wrist abduction. It is as follows.
AnyVector WristFlexion ={ 0.0,-87.0};
AnyVector WristAbduction ={ 0.0,-30.0};
There are no other movements in any other joints. I am getting the error which I have mentioned below.
I do not get any error when the value for either flexion or abduction is zero. Is there a way to increase the constraint and make the wrist achieve this motion?
I understand that we can increase the kinematics error tolerance but i don’t want to do it as it produces inaccuracies.
I tried changing the initial conditions as well. Kindly provide some solution.
