Dear Ajay,

Clearly the model has gone unstable, but you haven't provided enough information for me to guess as to why. Are you using a model NREL has provided (e.g. from the FAST v8 CertTest or OpenFAST r-test) or is this a model you made yourself?

Dear Ajay,

What do you mean by a "combined platform"? By "NREL Spar", presumably you mean the NREL 5-MW turbine atop the OC3-Hywind spar. What have you changed in this model?
