01Geometry remains legible

Mechanical members stay distinct so the assembly can be reviewed without a body shell obscuring the working geometry.

02Motion stays coordinated

Bump, roll, steer, and combined articulation use one synchronized review workflow across the available views.

03Evidence remains connected

Calculated characteristics and response graphs remain tied to the active assembly inputs and review state.

02

From assembly to evidence

Open one subsystem.
See what the geometry changed.

The assembly is not a disconnected visual. MetraBench carries its suspension definition into the component calculation, then returns the trends, margins, and review state to the same vehicle record.

Calculated suspension component

Read the response.
Keep it tied to the assembly.

In the app, these graphs read and display live data points from the track simulation. During playback, every curve marks the vehicle’s current operating point.

These coordinated curves use the released Vehicle Dynamics baseline: double-wishbone front, multi-link rear, and a ±75 mm rigid-link jounce sweep. Every axis, series, unit, and review boundary remains visible.

Questions

Know where
MetraBench fits.

Is MetraBench a replacement for FEA or CFD?+

No. MetraBench is designed for rapid sizing, screening, system studies and traceable preliminary calculations. High-fidelity simulation and physical testing remain essential where the design risk requires them.

Does it require an internet connection?+

Core calculations and local project work are designed to run offline. This helps teams retain control of sensitive project information.

Can calculations be reviewed later?+

Yes. Projects preserve calculation context, revisions, assurance information and report-ready engineering records.

Which platform will be supported first?+

The initial release is designed for 64-bit Windows as a signed desktop application and installer.
