There are two diagnostic messages for the Saturation block. The first message indicates
that the block is linearized outside of its lower saturation limit of -49, since the input
operating point is -49.05. The message also states the block can be linearized as a gain,
which will linearize the block as 1 regardless of the input operating point. To do so, first
click linearizing the block as a gain, which highlights the corresponding parameter in
the block dialog box. Then, select the Treat as gain when linearizing parameter.
