Altair Acquires Simsolid

Altair has announced that it has acquired Simsolid. Simsolid works on full-fidelity CAD assemblies to provide fast, accurate, and robust structural simulation without requiring geometry simplification, clean-up, or meshing. 

Its underlying technology is based largely on the work of Dr Victor Apanovitch, a former professor at Belarus Polytechnic University and the cofounder of Simsolid Corporation.

‘We believe Simsolid is a revolutionary technological breakthrough which will have a profound impact for product design,’ said James Scapa, Altair’s founder, chairman, and CEO, ‘It’s incredibly fast, accurate, and robust and we believe a game changer for our industry.’

The Simsolid computational engine is a commercial implementation of novel and unpublished mathematics based on extensions to the theory of external approximations. Simsolid controls solution accuracy using multi-pass adaptive analysis, making it extremely fast and memory efficient.  Large and complex assemblies can be solved rapidly even on laptop computers.

Dr Uwe Schramm, Altair’s chief technical officer, notes that, ‘We are very serious about solution accuracy.   Others have tried to accelerate the interface between CAD and simulation by degrading the mathematical robustness.   It is our feeling that by rapidly moving forward with the methods in Simsolid and expanding them across applications we can have a real effect on how design gets done while maintaining our high standards for computational excellence.’
