Variance

Explore the full design space before you simulate

Evaluate thousands of designs in minutes. Run high-fidelity simulation only on the best candidates.

Variance helps simulation teams replace sparse design sampling with broad exploration and selective refinement.

Grid of engineering component variants with highlighted top-performing candidates

Simulation speed limits design quality.

Each run takes hours or days. Only a fraction of possible designs are tested, and optimization loops are often impractical.

Engineers are forced to guess where to simulate.

Replace sparse sampling with full exploration

Variance lets teams evaluate the full parameter space, identify top-performing regions, and simulate only the top candidates.

Design decisions should not be limited by compute.
