Hello All!

Today I present you a SIMULIA 3DExperience R19x Tutorial!

You will first design a pipe using CATIA. Then copy you will insert abstraction shape to copy the original part. The partitioning will be performed in the abstraction shape.

We will add material and then apply a quad-dominant mesh to our part.

1. Step 1: Video

   
   

2. Step 2: Create the Solid Pipe

   * better to follow the video *

   Create a new 3DPart, call it "Solid Mesh Part"

   Sketch a profile (2 lines connected with a tangent semi-circle)

   In a plane normal to the profile, sketch a circle

   Use the feature Rib with the profile (center curve) and the circle (profile)

   Select the option "Thick surface" 3mm

   * the pipe is created *

3. Step 3: Apply Material

   Go to tools tab in the action bar

   Apply a material

   * the material library appears *

   Use the tag "Core Material"

   * a Covering material will not have the simulation properties *

   Select Aluminium for instance

   Apply the material to the part

   
   

4. Step 4: Create an Abstraction Shape

   Right click on the 3DPart and insert an Abstraction Shape

   * the abstraction shape is similar to a 3DShape. It allows you to copy the original part and do partitioning, remove fillet, chamfer, holes, etc. without transforming the original part *

   Double click on the 3DShape

   Right click on the Part Body

   Select "Copy"

   Right click on the Abstraction Shape

   Select Paste Special / As result with link

   * in that way, the original part is copied, and if modification are made, it will impact the copy *

   
   

5. Step 5: Partitioning [Part 1]

   Insert a geometrical set in the Abstraction Shape

   Double click on the 3DShape

   In the Rib, show the guide curve

   Copy the sketch

   Right click on the geometrical set in the Abstraction Shape

   Select Paste Special / As result with link

   * the guide curve is now copied in the abstraction shape *

   Switch to Generative Shape Design application

   Use an Extrude on top of the sketch

   -> Make sure that the surface is longer than the pipe

6. Step 6: Partitioning [Part 2]

   Insert a Finite Element Model in the 3DPart

   Call it Mesh Solid Part

   Double click on the Mesh

   * the software automatically switch to Structural Model Creation application *

   A panel appears, select the Abstraction shape for the Mesh

   in Action Bar, go to Model Preparation

   Click on the feature Partition

   A panel appears, select the pipe and the extruded surface

   * the pipe is now partitioned in 2 domains *

   Click again on the feature Partition

   Select the pipe and the vertical plane

   * the pipe is now partitioned in 4 domains *

   
   

7. Step 7: Mesh the part

   Switch to Mesh mode

   Click on Hex Mesh Partition feature

   A panel appears, select the type of element (linear or quadratic)

   Select the mesh size, 3mm in that case is correct (thickness of the pipe)

   Click on OK

   * the pipe is meshed *

   
   

8. Step 8: Analyze mesh (optional)

   Go to Check tab in the action bar

   Run a quality Analysis

   * You can see the quality and type of mesh element *

   
   

9. Step 9: Apply Properties

   Switch back to Model preparation mode

   Apply a SOLID property

   A panel appears, select the Body in Abstraction shape

   -> The Mesh should be automatically selected

   -> The Material should be automatically applied to property

   * The part is meshed and ready for Simulation Analysis *
