SPMM testrig and chassis templates with a Flex-body are generating an error.

I've replaced the ges_chassis body with a flex-body and run the assembly on the SPMM testrig. This generates an error.

This error appears to be common to all chassis templates in acar_shared and acar_concept databases when run on the SPMM testrig with the ges_chassis part replaced with a Flex-body except for _flex_chassis.tpl.
 
Has anyone generated a procedure or script to apply the entities in _flex_chassis.tpl to a standard chassis template like _rigid_chassis_bof.tpl ?
 
Any suggests would be appreciated.

    I got a chassis template that runs properly with a rigid chassis (see F98_spmm_rigid_chassis_01_spmm.msg). One hickup is the aero geforce has to be manually deactivated. That's a secondary issue as to why the aero gforce is not being deactivated by the submission macro:mac_ana_ful_spm_sub.
     
    The trouble is when I import an MNF for the ges_chassis body, and submit an SPMM analysis
     
    The trouble happens after the static equilibrium solution completes and the Quasi-Static starts and fails to converge.
     
    I've tested replacing the ges_chassis with the flexbody on the SDI testrig without a problem. Straight line, cornering, and full course simulations run fine.
     
    The issue is probably some joint or entity being activated/deactivated between the SVC suspension setup analysis and the Quasi static analysis. What ever is happening there is the problem.
     
    Any ideas would be appreciated.
