What SIDACT GmbH does

SIDACT GmbH is a privately held German software company headquartered in Bonn-Beuel, founded in August 2012 as a spin-off of the Fraunhofer Institute for Algorithms and Scientific Computing (SCAI). The company commercializes proprietary compression and analysis technology for numerical simulation results, originally developed at Fraunhofer since 2002 and protected by six patents exclusively licensed from Fraunhofer. Six Fraunhofer scientists transferred to SIDACT at founding, providing continuous technical leadership including the current CEO.

SIDACT's product portfolio centers on four families: FEMZIP, a set of compression tools for crash (LS-DYNA, PAM-CRASH, RADIOSS), NVH (NASTRAN), and CFD (OpenFOAM, EnSight Gold, MESHFREE, CCM+, ANSYS Mechanical) simulation outputs typically achieving 5–15x compression with up to 40x for modal NVH data; DIFFCRASH, a CAE tool for statistical robustness and scatter analysis in crash simulations; SDMZIP, a dimensionality-reduction based compressor for sets of related simulation runs; and FEMALYST, an automated event detection tool applying model order reduction and ML methods to flag anomalies in large simulation databases. The software integrates with major post-processors (LS-Prepost, ANSYS EnSight, ParaView, GNS Animator, Oasys D3PLOT, Hyperview, Beta MetaPost) and is delivered via ANSYS ACT extensions and on-the-fly decompression.

The company operates an enterprise sales-led model, selling licensed software directly to automotive OEMs and Tier 1 suppliers with global engineering footprints, complemented by regional distributors in the US, India, China, South Korea, and Japan, and a core European channel partnership with DYNAmore (the dominant LS-DYNA distributor). Revenue is generated through one-time and recurring software licenses plus support services; pricing is quote-based and not publicly disclosed. The customer base is concentrated in the global automotive CAE market, with Faurecia named publicly as a reference customer.

Revenue model

1. Software Licenses: SIDACT develops, maintains, and distributes licensed software products including FEMZIP, DIFFCRASH, FEMALYST, and SDMZIP. The company operates with a traditional software licensing model where customers obtain licenses to use the software products.
2. Software Licenses and Support Services: Products are designed for integration into batch processes for automated compression. On-the-fly decompression functionality is integrated into common post-processing tools. The company provides evaluation licenses and likely generates revenue from both initial licenses and ongoing support/updates.
