Hi everyone, I am practising implementing the composite overwrapped pressure vessel example in the above listed course. My simulation model however does not seem to run and gives the following error:
I could imagine this is due to how I have implemented the ply layers, but am not 100% sure as I followed everything else identical. Once creating the fabrics and and activating the orientation I get the following:
.

I applied 5 ply layers using the orientation described in the video file: 
1. Aluminium 

2. Carbon epoxy (-45)

3.Carbon epoxy (45)

4.Carbon epoxy (-45)

5. Carbon epoxy (45)

The order follows from my understanding that the first layer should be aluminium as per the task description (and because the orientation points outward) and then the respective carbon epoxy layers. 

 

Any help or assistance on understanding where I could have gone wrong would be greatly appreciated.
