ANSYS Workbench: Mechanical
Examples
Step 1. Opening ansys workbench
• Overview:
– Start > ANSYS Workbench
– Create Static Structural analysis system

Double click
[Optional] Note on save as …
• Do not save to a network drive location
– //server/share/folder/file.wbpj
• Instead used a local drive or mapped network
drive: browse computer, for example
– U:/folder/file.wbpj
• Reason: when solver tries to start, it will fail if a
file it needs is in a network drive location (even if
there is an equivalent mapped location). Can save
and re-open from the mapped location. To view
where your files are,
– Workbench menu > View > Files
Step 2. Geometry
• Overview:
– Sketch
• Draw
• Dimension
• Generate
– Extrude
• Generate
– Close the DesignModeler window
Double click, wait, then click

Click XYPlane
Click new sketch
Click Z axis
Click sketching tab
[Optional] Click Settings; Check boxes grid on and snap;
Major grid spacing 1 m; Minor steps 10; Click Draw
Note: navigating 3d view
• Zoom: mouse scroll wheel, or click buttons for
box zoom, slide zoom, fit all
• Tilt: press middle mouse button (scroll wheel)
and move mouse
• Pan: Ctrl+Middle mouse button
Note: making mistakes
• Use Undo/redo on toolbar
• Sketching > Modify > Trim to remove mistakes
• Zoom in close to make sure lines are closed.
Fix with trim and corner.
Click Draw Rectangle
Click one corner, then opposite

Step 3: Model and setup
• Overview:
– Mesh
• Create sizing rules
• Update mesh
– Loads
• Insert pressures
Double click
Wait till you see …
Select mesh. Change relevance center
or element size.

[Optional] More advanced rules: Right
click mesh and insert a rule.
Update mesh. (Toolbar or right click)
Note on mistakes in meshing and solving: if mesh is too
fine and never finishes, Start > run > taskmgr. Kill high
CPU process. Increase element size and retry.
Example medium relevance mesh.
Right click Static Structural > Insert >
Pressure
Follow the yellow boxes (unfinished)
Click geometry value, click a face, then
click apply

Select magnitude value and enter -100e3
Repeat (or duplicate and select
differenct face)
Step 4: Solving and viewing results
• Overview:
– Solve and wait
– Insert results
– Update results
– View results
Click solve, wait, and check for errors.
Warnings are ok, errors are bad.

Insert a result field: right click solution
> stress > maximum principal
Right click solution > evaluate all
results
Select maximum principal stress. Note
ratio of max to min values.
Advanced step: Parameters.
If the box is checked, parameter will be controlled differently.

As hole diameter goes to zero, max of maximum
principal stress goes to 2x boundary pressure.
