Model

The rectangle bar is a solid body. The material is polycarbonate.

On the Mechanical tab in the boundary condition dialog box, set the zero displacement on the fixed face.
Acceleration is taken care of in the Acceleration tab of Analysis Condition Setting.

Displacement

Select all X/Y/Z components.

UX=0, UY=0, UZ=0

Results

The Z-direction displacement is shown below by contour. The contour is the Z displacement.

The displacement is bigger towards the tip of the bar. It is approximately 49um at the tip.

The vectors of the mechanical stress are shown below.

The upper part of the fixed end is getting the tensile stress, whereas the lower part is getting the compression stress.

The external force and reactive force are listed in the table below.

The reactive force at FIX is 117.6[N] in +Z direction.
