could anyone tell me why i am getting this error and how to fix it ?

Dear @Riad.Elhamoud,

Iā€™m not familiar with the OpenFAST model you are running, but it sounds like your model is suffering an instability. A similar error was discussed in the following forum topic: Problem in MAP and MoorDyn.

Best regards,
