Depending on the formulation of the equations, in particular the compatibility conditions, the semi-discretization in space yields systems of differential-algebraic equations (DAE) in time of different indices. We present a DAE-index monitoring and discuss the numerical results for the application in a rotational 2d fiber spinning scenario.en003006519journal article
