LOG_STDOUT        | info    | Using sparse solver for linear system 22,

LOG_STDOUT        | info    | The maximum density for using sparse solvers can be specified

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.
LOG_SUCCESS       | info    | The initialization finished successfully with 3 homotopy steps.
LOG_STDOUT        | info    | Chattering detected around time 4147.91741518..5017.74653646 (100 state events in a row with a total time delta less than the step size 1802.85714286). This can be a performance bottleneck. Use -lv LOG_EVENTS for more information. The zero-crossing was: not pre(con.hysHea.y) and hvac.uHea > 0.05 or pre(con.hysHea.y) and hvac.uHea >= 0.01
LOG_ASSERT        | debug   | Aborting simulation due to chattering being detected and the simulation flags requesting we do not continue further.
