Hi,

I have attempted a simulation exercise on this assembly here in one of the innovation courses.

 After running the model, I apparently did not obtain the right answer for the normal stress which was supposed to be zero. Instead, I have only gotten 0.79MPa. Could it be due to me looking at the wrong place for it? Attached below are the relevant outputs and steps I have taken.  May I enquire as to where went wrong with my simulation and provide some suggestions for the causes? May I also trouble you to provide some elaborations for the solution as I am still new to Ansys? Thank you.

Hi 

Which course is this?

Pleae attach the course link so we can have a look in order to provide feedback.

Hi,

This is the course link for the course and its simulation exercise.

So for the question in that tutorial –in the normal stress probe you shown, the Z orientation is set, but in the Coordinate System, choose the Solution Coordinate System (not global) since it is asking for local z-direction (local z-dir. is thickness direction in the shell, hence why it is zero).

Hi,

Thank you, it worked out well.

That is great - all the best
