MBSLIM, revision 10513.
Coordinates: 180; natural (171)+relative (4 angles+5 distances), 3D.
Number of constraints: 178 (redundant).
Equations of motion: index-3 augmented Lagrangian formulation with projections of velocities and accelerations.
Integrator: trapezoidal rule.
Nonlinear system solution: Newton-Raphson iteration.
Projections: non-iterative penalty projections of velocities and accelerations.
Sensitivity method: ALI3-P direct sensitivity formulation. Forward differentiation with analytical derivatives.
Time step: 2.25d-3 s (fixed)
Penalty factor: 1.d4*(2.25d-3)=1.9753d9 (dynamics); 1.d6 (projections).
Programming language: Fortran 2018. |
