LOG_STDOUT        | warning | Sparsity pattern for non-linear system 0 is not regular. This indicates that something went wrong during sparsity pattern generation. Removing sparsity pattern and disabling NLS scaling.
LOG_STDOUT        | warning | The default linear solver fails, the fallback solver with total pivoting is started at time 0.000000. That might raise performance issues, for more information use -lv LOG_LS.
