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.

[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.

Note: Parameter Set

Can use to make parametric studies.
