Hi

 

So beam4 is a 2 node beam element. 

In mechanical one then needs a line body ( see here how to define such a line body

You have a 3D solid body which is meshed with HEX8 or HEX20 3D solid elements so hence the error.

To sum up the geometry created needs to be a line body not a 3D solid like you have, in order to use a beam4 element – look at the video again to see how to define/create a line body.

All the best
