Structural tower model in a studio setting

The product family

One discipline.
Five instruments.

Structural dynamics is not one job. Identification, monitoring, forced-response testing, benchmark generation, and code-based assessment each get a purpose-built product — connected where it matters by documented data handoffs, and nowhere else.

01 — The instruments

Purpose-built. Each one.

Flagship · OMA

Modal Master

Operational modal analysis for engineers who answer for their results. SHIPPING · STABLE CHANNEL

The defensible-identification OMA platform: nine identification engines, the closed-loop Deep Estimate, per-mode evidence trails, analytic uncertainty, HVSR site characterization, a full spectral-analysis bench, and branded reporting — on the desktop, on-premises. Its Hybrid FFT engine transforms records at any native length — no power-of-two truncation, no padding compromises — and its 3D visualization animates 800,000-node models at 60 Hz as measured on the development GPU, with headroom beyond a million nodes on stronger hardware.

The Modal Prediction Wizard closes the loop with design models: compare finite-element predictions against committed OMA modes with MAC pairing, and calibrate the model against measurement. For teams that want native finite-element modal solves of imported SAP2000 (.S2K) and ETABS (.E2K) models inside the workflow, the FE Engine is available as a separately licensed add-on module.

Monitoring

Modal Master SHM

Continuous structural health monitoring — the always-on sibling. SHIPPING · v1.2

Where Modal Master analyzes a campaign, SHM watches a structure: streaming FDD with batch SSI-COV re-identification, mode tracking that keeps physical modes matched across time (Hungarian assignment), environmental normalization to separate temperature from damage-relevant change, Hotelling T² statistical alarming, and a structure-level health index built for owners, not just analysts.

Forced-response testing

Modal Master EMA

Experimental modal analysis from measured FRFs — hammer and shaker work. WORKING PRODUCT · EVALUATION BY ENGAGEMENT

When you control the excitation, EMA is the tool: the full FRF estimator set (H₁, H₂, H₃, Hv, Hs) with coherence, impact-testing windows, CMIF mode indication, circle and line fitting, and its own identification pair — Peak Stabilization and Balanced ERA — with UFF 55/58 interchange for the lab ecosystem you already run.

Benchmark & simulation

Modal Master Signal Generator

Synthetic structural response with exact ground truth — the family's proving ground. SEPARATE DOWNLOAD · CONTACT FOR CURRENT BUILD

Every claim the family makes about accuracy traces back here: a generator that synthesizes multi-channel structural response — 18 structural presets, five excitation types, up to 64 channels — and writes the exact modal ground truth beside every dataset as JSON. Console automation scripts entire corpora; an EN 13791-oriented concrete path serves assessment workflows. It is the machine that builds the machines' exams.

Seismic assessment

CIVIA

Code-based building assessment driven by measured dynamics. WORKING PRODUCT · EVALUATION BY ENGAGEMENT

CIVIA turns identified modes into engineering judgment: building assessment under the Turkish seismic code (TBDY 2018), driven by measured modal properties instead of assumed ones. It consumes Modal Master's .mmoma.json export directly — the committed, evidence-backed mode set becomes the input to the assessment, with its provenance intact.

02 — How they connect

Documented handoffs.
Nothing else.

Each product is its own purpose-built codebase. Where they cooperate, they cooperate through documented data formats — three real handoffs, drawn exactly as they exist.

Modal Master SHMmonitoring pipeline exercise

The committed OMA result flows into assessment with its provenance intact; synthetic ground truth flows into certification; simulated streams exercise the monitoring pipeline before a single sensor is installed. These three arrows are the family's integration story — drawn honestly, because a diagram is a claim too.

A monitoring service, a test bench, and an identification desk are different jobs with different failure modes. We build them as separate instruments on purpose — each one small enough to be answerable for what it does.
