OS-environment detected: MDI_CDB_SEARCH=no
Adams Car will restore the cdb search algorithm from version 12.0 (if set to 'yes').
Usage of this environment variable is strongly discouraged.
OS-environment detected: MSC_ACAR_SIM_FAIL=legacy
Adams Car will ignore the driver control file 'haltOnFailure' setting and use the Solver 'simfail' preference, instead.
OS-environment detected: MSC_ADAMS_TIRE_DIS_M_AND_I=yes
Adams Tire will not re-distribute the total wheel mass and inertia over the rim and the belt when set to 'no'.
OS-environment detected: MSC_MULTILINE_XML=1
Adams Smartdriver will use multi-line formatting when instantiating xml driver control files (0 or 1; default=1).

---- START: WARNING ----
The Reconcile Acceleration-Force has detected a singular Jacobian matrix.
This problem may be caused by:
(a) A constraint equations that became almost redundant, e.g., the model
is at a singular configuration or at a bifurcation point.
(b) A massless PARTS in the model.
The Sparse Solver has detected row 145 has zero values (during the symbolic pivot selection).
The corresponding equation is: Part/92 X Force
A minimization algorithm will be used to find a solution on the
projected constraint manifold.
Simulation time is 1.000000000E+00
