"instruction": "Copy the supplied `/home/user/Desktop/damBreak_base/` template to `/home/user/Desktop/dam_break/` and run the fixed two-phase dam-break benchmark using OpenFOAM from the command line. Source the installed OpenFOAM environment before running OpenFOAM commands. For this workflow, before running the case, load OpenFOAM with `source /opt/openfoam11/etc/bashrc`; the solver binaries are under `/opt/openfoam11/bin` and its platform bin directory.\n\nKeep the template's five-block two-dimensional tank: `convertToMeters 0.146` gives overall dimensions `0.584 x 0.584 x 0.0146 m` and 2,268 cells. Initialize water only in the box `(0 0 -1)` to `(0.1461 0.292 1)` m and air elsewhere. Use stationary no-slip tank walls, the open atmospheric top, gravity `(0 -9.81 0)` m/s^2, surface tension 0.07 N/m, water `rho=1000 kg/m^3, nu=1e-6 m^2/s`, air `rho=1 kg/m^3, nu=1.48e-5 m^2/s`, and laminar momentum transport. Run `blockMesh`, require a successful `checkMesh`, run `setFields`, then run `interFoam` from `t=0` through the exact final time `t=0.5 s` with `maxCo=maxAlphaCo=0.5` and retain ASCII final `alpha.water`, `U`, and `p_rgh` fields. Save the command outputs as `/home/user/Desktop/dam_break/log.blockMesh`, `log.checkMesh`, `log.setFields`, and `log.interFoam`; a failed mesh check is not acceptable. At `t=0.5 s`, write the cell-centre field `C`. At target `x=0.25 m`, choose the mesh column whose cell-centre x-coordinate is nearest to the target, sort it bottom-to-top, and define `interface_height` as the first bottom-connected downward crossing from `alpha.water >= 0.5` to `< 0.5`, linearly interpolated to `alpha.water=0.5` between the two adjacent cell centres. Create `/home/user/Desktop/postprocess.py` that reads the final `C` and `alpha.water` fields, writes the complete selected column to `/home/user/Desktop/interface_profile.csv` with columns `y_m,alpha_water`, and writes `/home/user/Desktop/summary.txt` as one line containing `interface_height` in metres. Do not hard-code the result and do not use GUI tools.",
