Next generation structural simulation product for design engineers

MISSISSAUGA, Ontario, Canada. (January 4, 2016) – Altair SimSolid Corporation is proud to announce Altair SimSolid, the first structural simulation product with new technology created specifically for the design engineer. Most notable, Altair SimSolid contains new methods that eliminates geometry simplification and meshing, the two most time consuming and expertise extensive tasks done in traditional FEA. Moreover, Altair SimSolid can analyze complex parts and large assemblies not practical with traditional FEA and do it efficiently on a desktop class computer.

“Altair SimSolid solves a fundamental problem” says Altair SimSolid Corporation CEO Ken Welch, “being able to directly analyze fully featured CAD geometry without meshing opens simulation to a whole new group of users and applications.”
The Altair SimSolid computational engine is based on breakthrough extensions to the theory of external approximations. External approximations are a generalization of Finite Element Method (FEM) in terms that:

• absolutely arbitrary geometrical shapes can be used as “finite elements”
• basis functions which approximate field of interest in the part volume can be of arbitrary class and are independent of the volume shape

Altair SimSolid does not use the point-wise degrees of freedom (DOF) inherent in traditional FEA. Altair SimSolid DOF are functionals with geometrical support in the form of volumes, areas, line clouds, and point clouds. This provides the ability to handle geometrical imperfections, as well as assembly contact imperfections like gaps, penetrations and ragged contact areas.
What Beta users are saying

• “The ability to analyze large models without having to simplify them first is a definite timesaver” says Leif Erickson, VP Engineering, Cenairus Energy Services Ltd., Canada.
• “Altair SimSolid is the way to make the complex engineering problems easier” says Zoltán Szabó, CEO, Complex Engineering Ltd., Hungary.
• “Altair SimSolid, with its meshless technology, removes yet another barrier between having to be a specialist and getting a job done. It is structural analysis for everyone” says Christopher Schaefer, Engineer, Gardner-Denver Thomas Inc., USA.
