Can anyone help me with this error?

[H4yzeus]

I am trying to create a simple indentation simulation but I keep getting this error below.

doesn't that say it all ? you have several "elset" definitions, but none are this one.

 

[H4yzeus]

I am really new to ABAQUS so I genuinely have no idea what that means.

 

[3DDave]

It appears to mean that there is an assembly named B and there should be a set of constraints or surfaces or some other thing that is in it called "set 1."

Sometimes things like this happen when a clever user decides to rename things but not save the top level and all lower levels of the assembly that are affected by the name change.

 

[rb1957]

start learning the code by reading the manual, doing the tutorials, watching YT videos.

 

[FEA way]

Redefine those features (rigid body, contact) and it should work.
