  "instruction": "The starting input is an incomplete legacy FEniCS/DOLFIN Python script `/home/user/Desktop/poisson_base.py`. Run the script with the legacy `dolfin` API used by `poisson_base.py` (for example, FEniCS/DOLFIN 2019.1.0 and `from dolfin import *`), not the incompatible DOLFINx API. Run legacy FEniCS with `/home/user/miniconda3/bin/conda run --no-capture-output --prefix /home/user/miniconda3/envs/fenics-legacy python` when working on `poisson_base.py`.\n\nComplete the following: 1. Modify and generate `/home/user/Desktop/poisson.py`: - Complete the UFL variational form: `a = inner(grad(u), grad(v))*dx`, `L = f*v*dx`, where `f = Constant(-6.0)` - Call `solve(a == L, u, bc)` - Compute L2 error: `error_L2 = sqrt(assemble((u - u_D)**2 * dx))` - Compute H1 seminorm error: `error_H1 = sqrt(assemble(inner(grad(u - u_D), grad(u - u_D)) * dx))` 2. Run `poisson.py`. 3. Save error results to `/home/user/Desktop/summary.txt` in this format: `error_L2, error_H1`",
