Week 3- Geometry cleanup and Mid-surfacing
Case 1:
Aim: To extract mid-surface for the tube model and provide a connection with sharing option at the tube joint locations.
Objective:
To extact mid -surface for the tube modal and provide a connection with sharing option at tube joint location.
Procedure:
Open the cad model in ansys workbench.
Mid -surface
- Title bar > prepare > Midsurface > checked use selected faces option > selected the faces containing thickness of the tube > done > midsurfaces extracted it from parent geometry.
- Title bar > prepare > extend > selected the edges > extended it with trimmed surfaces option > done.
- Title bar > workbench > share > shared edges found > done
Aim: Create a model in Space claim one on top of each other and create a shared topology between the top block and the bottom block.
Dimension of Top Block A: 20 x 20 x 5 mm
Dimension of Bottom Block B: 40 x 40 x 10 mm
Boundary Conditions: Provide Fixed support for the bottom face of Block B
Procedure:
· Open the ansys work bench
- Tool box > analysis system > click on Modal > created modal analysis project tree in window.
- Add material and data to it in engineering data.
Create the Geometry in New space claim.
Dimension of Top Block A: 20 x 20 x 5 mm
Dimension of Bottom Block B: 40 x 40 x 10 mm
- Title bar > sketch > rectangle > checked define rectangle from center > 40 x 40 mm reactangle created.
- Add the thickness to component.
- Title bar > design > pull > selected the rectangle > pull along its y direction with 10mm length.
- Repeat the same process for the block A 20x20x5 mm
- Title bar > design > split body > selected the whole body > then selected the plane which is splitted into two bodies.
- Provide the connection Titlebar > workbench > share > selected the body > Done > shared the edges between the bodies.
Mesh
- Inorder to meshing of the blocks by the following steps.
- In ansys mechanical > project tree > mesh > method > automatic method > selected the geometry > Hex dominant method > done.
- Project tree > mesh > Sizing > selected the geometry > element size-2 mm > done.
- Project tree > mesh > generate mesh > meshed the blocks as shown in below
Boundary Conditions: Provide Fixed support for the bottom face of Block B
- In modal Analsyis Add maximum 10 nodes. Project tree > Modal > solution > solve > solved it.
