ERROR: Zero or negative volume for 3D-Element

Hi,

 

I am trying to simulate a honeycomb impact, with a honeycomb structure, in Radios. I am following the tutorial of a HoneyComb in Altair University, but in the start of the simulation running, this error appear: Zero or negative volume for 3D-Element.

 

I attach you the file.

 

Thank you in advance.
