Variance

Map thermal behavior across the full operating envelope

Identify hotspots, instabilities, and safe regions in seconds.

Variance enables fast thermal field exploration across nonlinear regimes, then focuses high-fidelity analysis where risk or performance is highest.

Thermal field visualization showing heat distribution across engineering component

Thermal systems are nonlinear and underexplored.

Design variables, materials, cooling, and usage conditions create a combinatorial space that is too large for brute-force simulation.

Critical edge cases are often missed.

Explore thermal response before failure occurs

Variance lets teams simulate the full operating envelope, detect high-risk regions early, and refine critical scenarios with full physics.

See the full thermal landscape, not isolated simulations.
