C="Trimmed Integrator Model
Automatically computes the initial condition of the integrator (x(0)) on the first pass of the simulation
such that the integrator input signal (xdot) is initially zero.
Limitations:
1. The Implicit Solver - Newton Raphson option MUST be selected for this model.
This is located under the SIMULATE - Change Parameter selection in the main menu.

C=" The merge block is used to modify the input to the constraint:
For the first pass of the simulation the input is xdot.
For each subsequent pass the input is set to zero (the constraint is satisfied).
This inhibits further implicit solution iterations."
