HELP Me pls. ABAQUS

[Leonid777]

I apologize for my English, I'm from Russia. I need to perform a crash test of the attenuator (impact), but I have some errors:

1053 elements have incorrect property definitions. The elements have been identified in element set WarnElemIncorrectProperty.

Node set assembly_karkas-1_karkas-refpt_ has no members and will be ignored. Nodes defined in this set may have been deleted because they were not connected to any elements.

Node set assembly_wall-1_wall-refpt_ has no members and will be ignored. Nodes defined in this set may have been deleted because they were not connected to any elements.

The project file in the attachment.

Please help me, what's wrong? There is no Russian instruction - it is very difficult to understand.

thanks!!!!

 

[FEA way]

To fix the first error make sure that materials, sections and element types are properly assigned to all parts.

For the second error, it seems that there are some redundant or incorrectly defined reference points. It will be best to delete them and create new ones.
