consolidation 2

1-D Consolidation — Finite Difference Solver

Explicit FD scheme with β = 1/6. Supports open (double drainage) and half-closed (impermeable bottom) layers. Interpolates coarse initial profile to a finer FD grid.

Coarse number of layers (im)

Total layer height h (m)

Coefficient of consolidation c_v (m²/s)

Time to compute t (s)

Refinement factor (default 10 → m = 10 × im)

Layer case Open (double drainage) Half-closed (impermeable bottom)

Beta (β)

Use formulaic n? YesNo (use dt from β)

Initial pore pressure input (coarse depths) 100,60,0

If values ≠ im+1, linear interpolation is applied.
