Week 3- Geometry cleanup and Mid-surfacing

Aim:- To extract mid-surface for the tube model and provide a connection with a sharing option at the tube joint locations. create a model in spaceclaim, and perform a model analysis.

• Case 1:- To extract mid-surface for the tube model and provide a connection with a sharing option at the tube joint locations.

  • open the space-claim and import the model, To import the model go>file>open and import your file as shown below.
  • 
  • To Extract the middle surface go>prepare tab>in the Analysis section click on midsurface.
  • 
  • After that select the surface click on the right button, then mid-surface extract.
  • 
  • After extracting the midsurface, click on the share option in the workbench tab.
  • 
  • we seen the ages glow in pink colour then we click on right button.
  • 
  • Then we saw some ages connected to the tube and some not connected; these are shown in red. Now we go to the Prepare tab> Analysis section extend option.
  • now select the ages and extend them. now the connection is ready.
  • 

  Case 2:

  Create a model in Spaceclaim 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

  Perform a modal analysis (free run) to verify connections and analyze the results.

  • open the workbench then open model analysis in the workbench after that open spaceclaim.
  • 
  • Now we create the geometry according to the question as shown below.
  • First create a rectangle 40*40 then click on return to 3D model and activate pull command and pull the surface to 10mm height.
  • 
  • 
  • Now we create a second block on the first surface and activate sketch mode select the rectangle and define the rectangle from the canter draw a rectangle 20*20 then click on return to 3D model activate pull command and pull the surface to 5mm height.
  • 
  • This model is a single body, now we separate them using the split body command.
  • 
  • now we create a connection between both bodies using the share option in the workbench tab.
  • 
  • Now model is ready then we go to workbench>model> and open the mechanical.
  • 
  • now the model is open in the mechanical, go to mesh >insert>method select all geometry and set Quadrilateral Dominant>insert sizing select the body and give element size 2mm then create.
  • 
  • 
  • In the model section insert the fix support in the bottom of the B block.
  • 
  • In an analysis setting we can set max modes to find that you want.
  • 
  • in the solution tab insert the deformation. than solve it.
  • 
  • To get the modeshape results select the data in frequency table>right click >create mode shape results from of total deformation than in project tree solve all results.
  •
