Zsimpwin Tutorial

This is the core function of the software. You must propose a circuit that physically represents your electrochemical system.

  • Connect Elements: Wire them in series or parallel.
  • Click OK or Apply to set the circuit.

    • ZSimpWin's plugin architecture allows for extending its functionality. Browse available plugins by clicking on Help > Plugin Manager. zsimpwin tutorial

    Cause: Infinite loop due to non-converging iteration (common with high φ >45° or high c >200 kPa). Fix: Press Esc. Reduce φ to 40° temporarily. If it runs, your soil is too strong for the iterative solver. Use the "Rigorous" vs "Simplified" toggles in the Settings menu. This is the core function of the software

    Since Zsimpwin has no "undo" button (horrifying, we know), adopt these habits: Connect Elements: Wire them in series or parallel

  • Parametric studies: Create a .txt input file via external editor. Use find-replace to change soil values, then import into Zsimpwin. It is faster than clicking.
  • Verify with hand calcs: Zsimpwin is reliable, but it does not warn you if you misuse a method (e.g., using drained parameters for a rapid load on clay). Always sanity-check: q_ult ≈ cNc + 0.5γBNγ + γDfNq.

    • If you want, I can create a complete sample netlist, run-plan, and a ready-to-fill essay template tailored to a specific circuit (name the circuit or provide component values).

    ZSimpWin is developed by EChem Software. Its primary function is to take your impedance data (Nyquist and Bode plots) and fit them to an Equivalent Circuit Model (ECM).

  • Output: Ultimate shaft resistance + end bearing. Compare to applied load.

    • Let us run a real-world example: A 2m x 2m square footing resting on a two-layer soil system.
