Adding weld constraint

Hi,

I have a model where I want to add a rectangular box that is held by both the hands of the model. In order to avoid closed-kinematic chain. I have added one weld joint between right hand and the box and want to create a weld constraint to the other hand. When I try to create weld constraint between Box and the left hand, I get the following error. What can be done to avoid this?. Is it possible to change the required tolerance level?.

Model unable to assemble: AssemblySolver::assemble() Failed: SimTK Exception thrown at assembler.cpp:897:
Method Assembler::assemble() failed because:
Unable to achieve required assembly error tolerance.
Assembly error tolerance achieved: 6.2633514485987973e-09 required: 1.0000000000000001e-09.
Model relaxing constraints and trying again.

Thanks in advance.

Regards,
Sanchana
