Lesson 04: Using Input Files

To create meshes that can be built through parameterization, the use of an input file will be required.

Goal

Using an input file, demonstrate how to reproduce the result from the previous lesson.

Steps

Verify the following files exist:

From the command line, first verify that version reports the SIBL Mesh Engine and the version number of the ptg package:

> conda activate siblenv
> version
SIBL Mesh Engine, ptg package version:
0.0.4

Then run pydual from the command line on the lesson_04.yml configuration file:

> cd ~/sibl/geo/doc/dual/lesson_04
> pydual -i lesson_04.yml
....
SIBL Mesh Engine initialized.
driver: /Users/chovey/sibl/geo/src/ptg/main.py
Dualization initiated.
input: lesson_04.yml
The database is {'version': 1.4, 'io_path': '~/sibl/geo/doc/dual/lesson_04/', 'boundary': 'circle_radius_2.txt', 'bounding_box': [[-2.0, -2.0], [2.0, 2.0]], 'resolution': 1.0, 'output_file': 'lesson_04_mesh', 'boundary_refine': True, 'developer_output': False, 'figure': {'boundary_shown': False, 'dpi': 200, 'elements_shown': True, 'filename': 'lesson_04_figure', 'format': 'png', 'frame': True, 'grid': False, 'label_x': '', 'label_y': '', 'latex': False, 'save': True, 'show': False, 'size': [8.0, 6.0], 'title': ''}}
