The Nonwoven Modeling Forum

November 25 and 26, 2025

Experience the world of digital modeling for nonwoven fabrics at The Nonwoven Modeling Forum, the live event designed for engineers, scientists, and newcomers with a focus on digital material development.

Practical sessions will cover the setup and validation of digital workflows, while live demonstrations will highlight the application of advanced 3D image processing and flow simulations using FlowDict and SatuDict in GeoDict, based on real-world scenarios.

A valuable opportunity to exchange ideas with peers and the Math2Market team, whether during open Q&A sessions or in a relaxed setting over dinner.
