@casella This was a project to compare the kinsol sover with the nox solver from Trilinos project . The Trilinos (https://trilinos.github.io/) project looks very promising to us. But unfortunately we had to stop the development due to lack of time.

Is there any documentation on how to access it from OMC?

It is documented in Qi Cheng Hua master thesis: "Numerical Simulation of Mechatronic Systems"
If you are interested I can send you a pdf version. The build is currently disabled because as Qi Cheng started the nox library was only suported for the gcc compiler.
It can be activated in the CMake file of the cpp runtime with the flag:
# use NOX non linear solver from trilinos library -DUSE_TRILINOS [default: OFF]
