"instruction": "Begin with a legacy FEniCS/DOLFIN transient heat-conduction template `/home/user/Desktop/transient_heat_base.py`. Run with the legacy `dolfin` API used by the template (for example, FEniCS/DOLFIN 2019.1.0), not DOLFINx. For this workflow, run legacy FEniCS with `/home/user/miniconda3/bin/conda run --no-capture-output --prefix /home/user/miniconda3/envs/fenics-legacy python` when working on `transient_heat_base.py`.\n\nComplete the following: 1. Modify and generate `/home/user/Desktop/transient.py`: - Complete the backward-Euler variational form - Implement `for n in range(100)` with `dt=0.1 s`, using the template's `alpha=50 mm^2/s`, initial temperature 20°C, left surface temperature 100°C, and natural insulated conditions on the other boundaries - Update each step with `u_n.assign(u)` - At `t=10 s`, extract the left-surface temperature and the temperature at `(5 mm, 25 mm)` 2. Run and save to `/home/user/Desktop/summary.txt`: Format: `surface_temp, temp_at_5mm`",
