[MBDyn-users] Singularity problem during derivatives computation

Dear all,

I have prepared an input model for NREL 5MW wind turbine. To debug the
model, I used the "abort after" option. The input and assembly are
performed successfully, but during the derivatives computation stage, the
following error is displayed.

Param_Manip(): divide by zero, probably due to singularity in rotation
parameters

How can I locate and correct this error in the model?

Regards,

Manoj K. Dhadwal
