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 2 1 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 2 3 1 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. 1 2 [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 2 3 1 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 2 1 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. 1 2 1 2 Note: Parameter Set Can use to make parametric studies. 3 2 1 As hole diameter goes to zero, max of maximum principal stress goes to 2x boundary pressure.
