Welcome to the VIG Assistant

I'm an expert in Vacuum Insulated Glass technology, drawing on Mihana Tech's research and the published VIG literature. Here's what I can help with:

Ask me about thermal performance, pillar design and geometry, low-e coatings, edge seal systems, vacuum integrity, residual gas effects, mechanical loading, glazing standards (NFRC, ISO), and manufacturing considerations.

Calculate — use the ⚙ Calculate button for guided thermal performance calculations (environmental & measurement modes, six pillar geometries, custom BCs, C* projection). For thermal stress, just ask me directly in chat — I'll run the calculation and show results here.

Thermal stress & failure assessment — ask me to calculate stress at any point on the VIG panel, or plot a stress profile along any line across the pane. Use the ⚙ Calculate button's Thermal Stress mode to run the guided calculator with an optional built-in failure assessment — choose a deterministic stress limit check or a probabilistic Weibull failure probability, embedded directly in the result. You can also ask me in chat afterwards: "What is the failure probability of the glass?" or "Is the glass safe under a 50-year atmospheric load?"

Plot & compare — ask me to plot any parameter sweep: U-value vs pillar spacing, emissivity, vacuum pressure, pillar radius, heat transfer coefficient, and more. I can overlay multiple series so you can compare configurations directly on the same chart.

References — technical answers are backed by inline citations from the peer-reviewed VIG literature so you can follow up in the original sources.
