Lesson 21: Flower

Goals

Mesh the flower domain using dualization, and compare the result to an alternative method and result published in Rushdi 2017, Figure 15.

Steps

Verify the following files exist:

• star.txt - the boundary x y discrete point definition
• lesson_21.yml - the YAML input file specification

From the command line:

> conda activate siblenv
> cd ~/sibl
> python geo/src/ptg/main.py -i geo/doc/dual/lesson_21/lesson_21.yml

Outputs

The following will appear in the specified io_path folder:

• Mesh file lesson_21.inp
• Image file lesson_21.png, and shown here:

	boundary for SHT method

Index

Next Steps

• Smooth the mesh.
• Compare minimum scaled Jacobian pre- and post-smooth.
