Assembly error

[Mojtaba Safari]

Hello, I have assembly error in my model, the error is:

Model unable to assemble: AssemblySolver::assemble() Failed: SimTK Exception thrown at Assembler.cpp:871:
Method Assembler::assemble() failed because:
Optimizer failed with message: SimTK Exception thrown at InteriorPointOptimizer.cpp:261:
Optimizer failed: Ipopt: Restoration failed (status -2)
Assembly error tolerance achieved: 0.00249382281276292 required: 1e-009.
Model relaxing constraints and trying again.

How can I fix it?

Thank you

Hello,

The only reason you have assembly failure is if you have constraints that can't be met to the desired tolerance in your model. Please disable the constraints in your model and check in the application how the model assembles.

Hope this helps,
