ANSYS Workbench: Mechanical Examples
Step 1. Opening ansys workbench Overview: – Start > ANSYS Workbench – Create Static Structural analysis system
2 1
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 1 2
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 1 2
Click Dimensions
Dimension steps Click the entity to dimension Click to place the dimension label Find the label in Details View Select and enter the value
Dimensions 1 2 3
Draw and dimension circle
Click Modeling
Click on the sketch
Click extrude
Under geometry, click apply
Select depth and enter a value
Generate
Close the window
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. 2 1
[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 1 2 3
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. 1 2

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.

Note: Parameter Set
Can use to make parametric studies
As hole diameter goes to zero, max of maximum principal stress goes to 2x boundary pressure.
