Hello proxicad
To check the bodies which have failed you can turn off the 'Mesh' at the top right corner of Discovery AIM screen as shown in the image below.
Then right click on the 'Mesh requires attention' message and choose 'Select Location'.
This will highlight the failed region as shown in below image.
Is this what you were looking for? If not could you please elaborate what is the issue you are facing?
