Hello Arnaud,
Which version of LS-DYNA are you using? The developer said that this error message is only in R12. The developer also suggested the following:
"It seems there is intersection of the initial surface mesh. I would suggest the customer switch to a later version of DYNA, the error message after R13 has improved and should show more and clearer information to the user.
For the latest version it can show the location of the intersection so it is easier for the user to find where goes wrong."
