ich habe das Docker-Image mit deinem Repository auf meinem Windows-PC zum Laufen bekommen. Allerdings läuft fenics nicht. Zum einen passen die Verzeichnisse nicht zur Doku (nicht so schlimm, sollte aber am Ende passen).
Ich habe in examples/lid_driven_cavity `python3 ../../src/fenicsR13.py input.yml` probiert, und folgendes bekommen:
```
{'bcs': [{3000: [{'gamma_w': ['required field'], 'name': ['unknown field'], 'p_w': ['required field'], 'u_n_w': ['required field']}], 3100: [{'gamma_w': ['required field'], 'name': ['unknown field'], 'p_w': ['required field'], 'u_n_w': ['required field']}]}], 'convergence_study': [{'relative_error': ['required field'], 'rescale_pressure': ['required field']}]}

Was sagst du?Lambert TheisenManuel TorrilhonLambert Theisenhttps://git.rwth-aachen.de/lamBOO/fenicsR13/-/issues/9Simplify Mesh Generation2019-10-11T17:05:08+02:00Lambert TheisenSimplify Mesh GenerationBased in #8, the `h5`-mesh generation seems to be not intuituve.
Therefore: Find nicer way of mesh generation. Maybe include the steps of the `create_meshes.py` into an external program.Based in #8, the `h5`-mesh generation seems to be not intuituve.
