    88Aha, I missed that.

    10 I prepared two updated test models {{{TestIndexReduction3}}} and {{{TestIndexReduction4}}} where I terminated the circuits with a delta-connected resistive load, so that we have the constraint that the three currents are zero.
     10I prepared two updated test models {{{TestIndexReduction3}}} and {{{TestIndexReduction4}}} where I terminated the circuits with a delta-connected resistive load, which more accurately reflects the structure of the original MSL model.

    1212In the case without rectifier and inverter ({{{TestIndexReduction3}}}), OMC correctly identifies the constraint and performs the right index reduction. In the other case {{{TestIndexReduction4}}} it fails to do so and ends up with an index-2 DAE, that causes the runtime solver to fail.
