A project focusing on a finite-element method formulation-based straight 3D parametric optimizable Timoshenko beam
Motivated but not limited to usage in education as well as for research purposes
With effort made to be compatible/usable with the interface of Kratos Multiphisics

Test scripts are in source/test_scripts and can be executed from run_all_tests.py which discovers and runs all of them. If you wish to run individual tests, you'll have to navigate a terminal to the project's source directory, and run them as modules like so:
python -m source.test_scripts.test_beam_eigenvalue_analytic
Each test script uses python's unittest framework, so you can pass any argument that unittest recognises.
Some tests store their references in text files (stored in source/test_scripts/reference_output) and compare their results against them. These text files can be regenerated by passing --generate-references to the test script you wish to update references for.
If you wish to run a specific test case using a debugger, you'll have to write a script that imports and executes the desired case, and run that in the debugger. An example of such a script:
import source.test_scripts.test_beam_eigenvalue_analytic
from source.test_utils.test_case import TestMain
case = source.test_scripts.test_beam_eigenvalue_analytic.BeamEigenvalueAnalyticalTest
TestMain()Run all working relevant tests by:
python -m source.test_utils.run_all_tests
