Altair acquires SIMSOLID, game-changing simulation technology for designers, design engineers, and simulation analysts


Altair announced in October that it has acquired SIMSOLID, a company founded by asking a simple question: Why does the geometry used in the design and structural simulation worlds have to be so different?

Based in Mississauga, Ontario, SIMSOLID works on full-fidelity CAD assemblies to provide fast, accurate, and robust structural simulation without requiring geometry simplification, cleanup, 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.


We believe SIMSOLID is a revolutionary technological breakthrough which will have a profound impact for product design,” said James Scapa, Altairs CEO, Its 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The SIMSOLID computational engine is a commercial implementation of novel and unpublished mathematics based on extensions to the theory of external approximations.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, Altairs 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.

SIMSOLID is structural analysis software developed specifically for design engineers. It eliminates geometry simplification and meshing, the two most time consuming and expertise extensive tasks done in traditional FEA, said Schramm.

Moreover, itcan analyze complex parts and large assemblies not practical with traditional FEA and do it efficiently on a desktop class computer. Both fast and accurate, itcontrols solution accuracy using a unique multi-pass adaptive analysis, said Schramm.

Apanovitch is cofounder, president and CTO at SimSolid. A CAE industry veteran, Victor has worked in executive roles for over 20 years. Formerly a professor at Belarus Polytechnic University, he is the author of the book The Method of External Finite Element Approximations.
