Altair SimSolid: mesh free revolution in structural analysis
Edited By Editorial Staff -

Altair SimSolidTM is a technological breakthrough that allows civil engineers to analyze fully featured CAD assemblies in minutes, eliminating geometry simplification and meshing.

SimSolid has had a profound impact on the world of structural design, specifically for Architecture Engineering and Construction (AEC) companies focused on rapidly evolving and changing designs. With SimSolid, design teams can perform multiple iterations of their most complex parts and explore multiple alternatives of large assemblies at blazing speed.

To learn more about its functionality and features, you can participate in the free Altair webinar on October 29th, where you can listen directly to the experience of the company Faraone, producer of lightweight structures and advanced glass systems.

5 good reasons to understand Altair SimSolid

  1. Steel building designs in record time
    With no need for CAD clean-up and FEA meshing, structural engineers and façade engineers can use SimSolid to meet deadlines and avoid costly redesign cycles. SimSolid reads raw and imperfect CAD, and in minutes, can simulate and evaluate large structural models without the effort required of a classical FEM approach. SimSolid handles any size of structural model, including those comprised of hundreds of parts and connections. SimSolid is ideal for both FEM veterans and for companies without dedicated FEA specialists that still want to perform structural analyses.
  2. Foresee better alternatives in large structural models
    Today, product design cycles have two crucial requirements: product performance and timely delivery. Due to immense project delivery pressures, there is often insufficient time to investigate design alternatives or new solutions. SimSolid’s ability to import and quickly solve complex CAD allow users to easily explore a large range of design alternatives to find better solutions within existing project timelines.
  3. Nonlinearity made easy
    The real world is nonlinear, so understanding the nonlinear behavior of structures is critical to effective AEC design. Façade systems, however, are traditionally difficult to simulate due to their complex connections like bolts with pre-tensioning, weld lines, and the contacts and friction effects between hundreds of parts. Additionally, material non-linearities such as large deflections and plastic deformation further complicate the analysis process. SimSolid offers all of these features in the standard solver package, making it possible to analyze these essential nonlinear effects from the beginning of the design process. And SimSolid does not require expensive hardware to deliver fast results. Complex models run in minutes on a standard laptop!
  4. Rock solid math under the hood
    SimSolid technology is based on extensions of fundamental concepts of FEA, in particular, on the redefinition of the basic ideas of degrees of freedom (DOF). SimSolid does not use the pointwise DOF inherent in traditional FEA. SimSolid DOF are functionals with geometric support in the form of volumes, areas, line clouds, and point clouds. This provides the ability to handle geometric imperfections as well as assembly contact imperfections, like gaps, penetrations, and ragged contact areas.SimSolid’s accuracy has been independently validated by NAFEMS.
