Advanced Modeling and Meshing Techniques for 3D Analyses

This resource explores various modeling approaches for 3D analyses, focusing on extrusion and swept meshing techniques. The extrusion method allows users to take a 2D area and extend it into a 3D volume by defining an axis through keypoints. Additionally, cylindrical coordinates can be utilized for extrusion. Swept meshing technique is discussed as a way to convert 2D elements into hex elements, making it easier to mesh volumes. Proper line divisions in the corresponding area are critical for successful mapping and mesh generation.

  1. Modeling and Meshing for 3-D Analyses Fall 2007

  2. Some Modeling Approaches • Extrusion – Take an area and “extrude” it into a 3-D volume (Modeling/Operate/Extrude/Areas)

  3. Extrusion (continued) • You can also extrude about an axis • Axis is identified by keypoints

  4. Extrusion (continued) • You can extrude in cylindrical coordinates

  5. Swept Meshing • Sweeping can help us mesh with hex elements • Just mesh an area with 2-D elements and then sweep to volume

  6. Mapping • Works for areas made of 3 or 4 lines • Make sure all lines have right number of divisions • Mesh one area
