Advanced FEM analysis and code verification for any glass geometry, web app and Grasshopper plugin.
GLASSS is a web application by Maffeis Engineering S.p.A. for structural engineers and façade designers.
Model a glass panel (shape, layers, interlayers, supports and loads), run a finite element analysis on our servers and check stresses and deflections against European or American standards.
Every analysis produces a detailed PDF report.
Grounded in research published in the International Journal of Solids and Structures - open science.

Stresses from rapid temperature gradients - proactively identify thermal cracking risk.

Pendulum and hard-body impact simulation - failure limits and post-breakage residual capacity.

Internal stresses in cold-bent facades including geometric nonlinearity and interlayer coupling.
Parametric verification for every glass shape directly in Rhino's Grasshopper environment.
Choose shape, design the geometry, the curvature, the built up angle and the layers, eventual interlayers and relative material.
Add support points, edge supports types and spacers.
Add the load types and build the load combinations, you can set self wight, wind pressure, wind suction, snow, barriers, points, climate and altitude loads.
Set the verification standard and options, review design values and set deflection option.
Run analysis and see the results for displacements and stresses for every load combination.
Prototype neural network trained on glass configurations. Independent from the FEM, it quickly estimates stresses and deformations with order-of-magnitude accuracy.
Check strength and deformation working ratios.
Generate a PDF report with all the details.
From blank canvas to verified glass panel - complete walkthrough.
