Hello

I encountered a  problem yesterday concerning the Non linear analysis with optistruct certification program and to be more exact in the quizz related to hyperelastic part (quizz 5), I believe that the question 1 must be updated in the quizz, because I performed the analysis as requested and had the same results of element strains (von mises) equal to that shown in the hyperelastic analysis in the pdf which confirms that the analysis was done as requested from my part. I failed the attempt only due to first question contact traction (534 was the value I got) which had answers way above what I got in my analysis (quizz had answers such as 1159 and above), but the second and third questions I got the correct answers, therefore the first question was the reason I failed the attempt, since I got the second and third questions right.

Therefore I believe that the first question must be updated, and I invite the moderator to perform the analysis with the 2022 hypermesh to compare the results of the first question with that received from the analysis. I hope we get a reply as soon as possible or an update because I paused my progress in the non linear analysis because I dont want to waste my attempts because I peformed the analysis more than once and everytime I get the same results, which led me to believe the first question must be updated. 

Thank you.
