ZSimpWin Tutorial — Quick Report

3) Run simulations and capture outputs

• Run .op to verify bias points.
• Run .ac to get magnitude/phase of nodes; export Bode data.
• Run .tran with a steady-state input to capture waveforms; use zoom and cursors.
• For THD: perform FFT on the output waveform (ensure enough cycles and sample density).
• Save plots and raw data (export CSV where possible).

Part 7: Zsimpwin vs. Modern Alternatives (2025 Update)

| Feature | Zsimpwin | Plaxis 2D | Geo5 | Excel Sheet | | :--- | :--- | :--- | :--- | :--- | | Cost | Free / Legacy | $5k+/year | $2k+ | Low (time) | | Learning Curve | Moderate (clunky UI) | High | Low | Variable | | 3D Visualization | No | Yes | Yes | No | | Settlement Speed | Instant (elastic) | Slow (FEM) | Fast | Instant | | Best For | Quick checks, students | Research, complex geometry | Professional design | Custom scripts |

Verdict: Use Zsimpwin for preliminary design, classroom learning, and rapid sensitivity analysis. Use Plaxis or Geo5 for final design submission. zsimpwin tutorial

Error 4: "Cannot find file .DLL"

Cause: A missing Visual Basic or Fortran runtime. Fix: Install Microsoft Visual C++ Redistributable 2008-2022 and vbrun60sp6.exe. ZSimpWin Tutorial — Quick Report 3) Run simulations

4.2 Consolidation Settlement (Time-Dependent)

Go to Soil → Advanced Properties.

• Input Cv (coefficient of consolidation, m²/year) and Cc (compression index).
• Under Analysis → Settlement, choose "Terzaghi 1D Consolidation".
• Specify time steps: 1 month, 6 months, 1 year, 50 years.
• Output: A time-settlement curve. For a 5m clay layer, you might see 70% consolidation after 8 years.

Output Metrics to Check

• Vertex count, face count
• File size
• Surface deviation (if provided) — max/mean error vs original
• Texture UV distortion (visual check)

Example: Tuning a First-Order + Dead Time (FOPDT) System

Process: ( G(s) = \frac1.510s + 1 e^-2s ) Part 7: Zsimpwin vs
