Surface Mesh Partitioning SIMULIA 3DExperience

Hello Hello!

Here is another video about SIMULIA 3DExperience R19x! 2 weeks ago I published a tutorial for SOLID meshing in SIMULIA Application (https://youtu.be/dnP31eBoB4g). So this time it will be about SURFACE meshing.

It is a bit different because the partitioning will be performed on Generative Shape Design with the feature split.

You will copy the original design in the abstraction shape and apply a material to the 3DPart.

Then you will finish by applying the mesh to the surface by using the constraint lines previously created from the split.

  1. Step 1: Video


  2. Step 2: Create a Surface Pipe

    * better to follow the video *

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

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

    Use the feature Sweep with the option "Center & Radius"

    Select the center curve and a radius of 25mm

    * the pipe is created *

  3. Step 3: Apply the 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 sketch in the geometrical set

    Select "Copy"

    Right click on the Abstraction Shape

    Select Paste Special / As result with link

    Do the same with the sweep.

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

  5. Step 5: Partitioning

    Switch to Generative Shape Design application

    Use an Extrude on top of the sketch

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

    Go to properties, color the Extrude surface (in order to differentiate it from the pipe)

    -

    Use the feature split between the Pipe and the Extrude

    * the Part is now partitioned in 2 domains *

    Use the feature split between the Pipe and the vertical Plane (in that case YZ-plane)

    * the Part is now partitioned in 4 domains *

    -

    Join all the domains together

  6. Step 6: Mesh the part

    Insert a Finite Element Model in the 3DPart

    Call it Mesh Surface 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 Mesh mode

    Click on Surface Quad Mesh

    Select the Join as a support

    Click on Quadratic element type

    Initialize the element from geometry (in that case 17mm)

    Click on Mesh

    -> the mesh is too big

    Insert 10mm as a value

    Click on Mesh

    * the pipe is meshed *

  7. Step 7: Refine the Mesh [Part 1]

    In the Surface Quad Mesh panel, you can edit the mesh

    * The app automatically switch to another view mode *

    Hide the part and the mesh in order to just show the boundaries of the mesh

    Switch to Shading with no edges for a better result

    Pick all the boundaries

    * You should have this result (all blue lines should be yellow) *

    Show the part and the Mesh again

    Exit the edition mode

    * The Mesh is updated and it is linked to the boundaries *


  8. Step 8: Refine the Mesh [Part 2]

    Edit the Mesh again

    Select the Mapped Mesh Feature

    * This mode will give a nice orthogonal grid mesh on the surface *

    Insert 5mm value for the size of the mesh

    Continue this manipulation with all other domains

    * You can even lock the domain you have made previously *

    Exit the mesh edition

    * The mesh is updated *


  9. Step 9: 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 *

  10. Step 10: Apply Properties

    Switch back to Model preparation mode

    Apply a Shell property

    A panel appears, select the Join 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 *
