How can you save time using 2D advanced meshing?

2D advanced meshing in CATIA V5 is a feature within the advanced meshing tools workbench that enables users to create finite element models for parts with constant thickness, such as sheet metal. By using 2D elements (e.g., shell elements), this method reduces computational time and resources compared to 3D meshing while maintaining accuracy for specific applications like structural analysis. To perform 2D meshing:

Prepare the geometry:

• Extract the mid-plane of the part using the extract tool (insert > operation > extract) and offset it if necessary (insert > surfaces > offset) in the generative shape design workbench.

Launch the advanced meshing tools workbench:

• Navigate to start > analysis & simulation > advanced meshing tools.

Select the analysis type:

• Choose the type of analysis (e.g., static analysis) and confirm.

Apply surface meshing:

• Use the advanced surface mesher tool to select the mid-plane surface.

Specify mesh parameters such as:

• Mesh size: defines element size.
• Sag: controls curvature approximation.
• Min hole size: suppresses small holes below a defined diameter (set to 0mm to retain all features).

Refine and edit mesh:

• Adjust or transform mesh elements as needed using tools in the meshing editor.

Finalize for analysis:

• Apply material properties, boundary conditions, and loads in the generative structural analysis workbench.
• Assign 2D properties (e.g., thickness) to the meshed part before running the simulation.
