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.

Step 1: Video
-
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 *
-
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
-
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 *
-
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
-
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 *
-
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 *
-
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 *
-
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 *
-
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 *
