# Numerical Results

If you have followed the instructions in this tutorial you should obtain the following results.

#### Deformation

Total Deformation

X Deformation

Y Deformation

#### Stresses

Direct Stress

Minimum Bending Stress

Maximum Bending Stress

#### Reaction Forces

Left Support Reaction Force

Right Support Reaction Force

#### Moment Reactions

Left Support Moment Reaction

Right Support Moment Reaction

#### Local Coordinate System

Bending moment and shear force are reported in the local coordinate system. To determine what the local coordinate system is for each element, highlight Solution in the tree and select Coordinate Systems > Element Triads.

Click on Solve and ANSYS will display the local coordinate system for each element. The local x, y and z are shown in red, blue and green (RGB), respectively.

#### Shear Force

From the local coordinate systems above, we see that we need the shear force in the local y direction. To get the shear in the local y, highlight Solution in the tree and select Beam Results > Shear Force.

Under Details, change Type to Directional Shear Force.

Click on Solve. This will color each element according to the value of the shear force. To probe the shear values in the graphics window, first make ANSYS wrap the cross-section around the line elements by going to the main menu and selecting View > Thick Shells and Beams.

Then select Probe in the main menu. Now you can hover over the structure to see the value of the shear force. If you click at a point, it will add a label at that point showing the value.

If you need to get the exact values at particular locations, it is better to make a plot along a "path" rather than use "probe". We show that next.

#### Bending Moment along Path

Create the path.

(Right click) Model > Insert > Construction Geometry

(Right click) Construction Geometry > Insert > Path

Turn on "edge selection".

Under Path Type, select Edge. Then click on any edge and click Apply under Geometry.

Highlight Solution in tree and select Beam Results > Bending Moment. Change Scoping Method and Path to Path. Change to Directional Bending Moment in the local z direction.

Click Solve. The tabular data (lower right) gives the bending moment values at the beginning and end of the path. You can export the tabular data into an Excel file by right-clicking on it.
