Python class to read UNV files produced by Simufact 2021.

Simufact_UNV_reader

Python class to read UNV files produced for Simufact 2021.

For who this code is?:

This code is intended for people using Simufact 2021 and would like to import unv results in python.

Installation:

1. Copy unvreader.py in your project
2. Install the requirement with pip install -r requirements.txt
3. Import the Unv_process class in your code with from unvreader import Unv_process

Example

from unvreader import Unv_process

UNV_FILE = r"examples\surface-cantileverXbeam-mm_76.unv"

unv = Unv_process()
unv.load_file(UNV_FILE)
unv.generate_mesh()

# Print the printing time of the simulation
print(f"Time: {unv.time_human}")
# Print the available data in the unv file
print(unv)

# Display
unv.display_data("displacement_vector")

Text output:

Comparison between Simufact display and display_data:

(The base plate was not extracted in the unv file)

Available functions:

• load_file(path: str): Used to load the UNV file. This will parse the UNV file and add the extracted results to the object.
• generate_mesh(): Will generate the mesh using trimesh and the data contained in the UNV file.
• display_data(key: str): Map on the mesh the extracted value from the key. In case there is multiple data per vertices, the mean of those value is displayed.

Available variables:

• time_human -> str containing the simulated time for the simulation.
• keys -> list list of all available results. Can be displayed by printing the object as show in example.
• keys -> ndarray: numpy array containing the results.

Limitation

This reader is not an official one as is provided as is. The UNV files are providing some information that are not used in this reader such as:

• Faces informations:

• Vertices information:

Errors

ImportError('no graph engines available!'):

This errors is due to the installation of trimesh. To solve this problem, run this command: pip install trimesh[easy] or pip install trimesh[all]
