As I am completing the certification for Non Linear Analysis with OptiStruct Advanced Examination exam the quiz is locked. I have completed 3 attempts in the Bolt pretension about 3/4 of the quizz and further, no attempts are allowed can I get one more attempt to complete certification?
Also i think a few questions could be phrased better cause they are a bit ambiguous ( ie It asks wether 1D bolt pretension uses 1D rigid elements . In my understanding it does use both rigid(RBE2 web) and non rigid elemets (in form of CBEAM, CROD, CBAR) however the pretension is applied in the non rigid elements so it is not clear what the answer is.
