I am trying to run an restart analysis on an Explicit model where I wrote out the restart files using the overlay option:

*Restart, write, overlay

When I run the restart analysis, I get the following error (a whole of times), which looks like it's because Abaqus is unable to read some element definitions

 ***ERROR: SYSTEM ERROR IN SMAPRE_CONTTABLESREALBEAMCROSSSECT - ELEMENT NOT FOUND

Unfortunately, I am unable to share my input decks in public, but is there anything here that gives a clue as to why I might be getting these errors.  The model contains beam, shell and solid elements and a number of beam profiles.  

Any pointers greatly appreciated. 

Thanks.
