W10_lab.ipynb
(Colab) |
In-class lab: the exponential law in NumPy, an imperfect interface
reproduced exactly (and the ‘+’ trap with -np 2), a
snap-back traced exactly with opening control (and displacement control
jumping over it), the source’s plate with two inclusions debonding
between perfect bond and holes, LLM exercise (two bonded layers) |
in class (≈ 80 min) |
W10_HW9.ipynb
(Colab) |
HW9 — the exponential law, snap-back and springs in series (theory), the bilinear law against the exact strip, brittleness against the strip length, springs on every facet against h and K, counting the ‘+’ sides, where and when the inclusions debond, an LLM-generated interface script with defects | due before Week 11 |
../dolfinx_0.11_api_reference.md |
DOLFINx 0.11 API reference sheet — §16s interfaces between submeshes, opening control — paste it into your LLM | always |
Open a notebook in Colab: click its link on the
course page or below — it opens in Colab; then File → Save a copy in
Drive and work on that copy. (Or upload the .ipynb to
Google Drive → right-click → Open with → Google Colaboratory.)
Run the setup cell first (≈ 3–5 min); re-run it after every runtime
restart.
Where code can run: basix,
ufl, dolfinx, petsc4py are used
only inside %%fenicsx cells. Ordinary cells have NumPy and
matplotlib only. The model is one module written by the
%%writefile /tmp/fnx/czm.py cell — run it first. All cells
run with -np 2.
Before submitting: Runtime → Restart session and
run all, fill in the AI-usage log, download the
.ipynb. An error inside a %%fenicsx cell does
not stop Run all: the traceback is printed and
the next cell runs anyway. Scroll through every output before you
submit. (The first cell of HW9 Q7 runs an LLM-generated script that is
meant to be wrong.) The lab runs in about a minute locally, HW9
in about two (a few minutes on Colab).
Week 11 starts with a 10-minute quiz on this week’s lecture (closed-AI).
