The model you have shared does not form a closed volume. That is the reason it is unable to generate an inlet and outlet You may want to check the two surfaces (refer image below) before creating inlet & outlet.
The deformation chart shows the maximum deformation in the selected direction (X, Y or Z). The x-axis of the chart denotes design points. If you have multiple design points the graph plots, automatically, with the deformation on the y-axis and design point on x-axis.
