Model dimensions and properties

The model has the following dimensions:

$\begin{array}{rcl} n_x &=& 3\\ n_z &=& 0\\ n_u &=& 1\\ n_p &=& 0\\ n_c &=& 0\\ n_{r^\mathrm{i}} &=& 0\\ n_{r^\mathrm{e}} &=& 3 \end{array}$

It is thus an ODE model. The interior point equality conditions fix the initial values of the differential states.
