Siemens Adds Multiscale Chemistry Modeling to Xcelerator Portfolio with Acquisition of Culgi

By David Humphrey

Acquisition or Partnership

Siemens announced that it has signed an agreement to acquire Culgi, a computational chemistry software company with a focus on multiscale simulations in the process industries.  Culgi will join Siemens Digital Industries Software, where its Multiscale Chemistry Modelingsolutions will expand simulation capabilities of the Xcelerator portfolio with quantum and molecular chemistry models that seamlessly couple with the continuum approach in Simcenter STAR-CCM+ software.  This unique engineering workflow can deliver cost savings and accelerate innovation in the materials and process industries, increasing the potential for product and process transformations.

 The acquisition of Culgi builds on Siemens’ November 2019 acquisition of MultiMechanics, which added efficient prediction of solid material properties and behavior to the Simcenter portfolio.  Through the addition of Culgi’s soft materials simulation, Simcenter can now offer a unique integrated CAE solution that enables performance-driven optimization of advanced materials.

 Founded in 1999 in Leiden, The Netherlands, Culgi provides expertise and develops software solutions for multiscale chemistry simulation, from quantum chemistry to molecular dynamics.  Its products are used by companies to design and analyze new materials in domains, such as specialty chemicals, batteries, pharmaceuticals, and cosmetics.  The transaction is expected to close in calendar year 2020.  Terms of the transaction were not disclosed.
