参考 libMesh::SolverException::error_code , 以及 libMesh::SolverException::what_message.

     // returned by a PETSc function :)
     PetscErrorMessage(error_code, &text, &specific);
 
     // Usually the "specific" error message string is more useful than
     // the generic text corresponding to the error_code, since many
     // SETERRQ calls just use error_code == 1

参考 libMesh::SolverException::what_message.

   {
     // std::string::c_str() is noexcept in C++11, so it's safe to call
     // in what() because it can't throw.
     return what_message.c_str();
   }
