Options are LINEAR, STRING, NONLINEAR.

OS-environment variable
MSC_USE_FORTRAN_STYLE_RELOAD_MESSAGE_FILE=1
Asol SDK. Enforces Adams Solver (C++) to use the Adams Solver (FORTRAN) message file style when reloading.

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: COSIN_PREFIX=C:\Program Files\MSC.Software\Adams\2019_2\cosin
Adams FTire will use the user specified path to the cosin software installation.

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).

OS-environment detected: COSIN_EXTLIB_OPENCRG=C:\PROGRA~1\MSC~1.SOF\Adams\2019_2\win64\OpenCRG.dll

RE: error in adams/car driveline

You don't seem to be using a static funnel, try that. Other options include using a different Solver, increasing MAXIT (400 is none too many) and changing the ERROR setting. Or of course you may have a horrible mistake in your model.
