New Altair SimSolid Professional edition

We are please to announce our latest product edition, Altair SimSolid Professional. Read on to find out more.

Created for our most demanding customers, Altair SimSolid Professional edition has all the features of Power but extends further in three main areas: CAD connectivity, analysis breadth and connection automation.

CAD connectivity

All Altair SimSolid editions are CAD integrated. Today, we support Onshape, SOLIDWORKS, Autodesk Fusion 360 and STL. SOLIDWORKS and Fusion 360 use CAD embedded plugins to seamlessly transfer data directly to Altair SimSolid. This requires that the CAD application is open and available; something that is not always possible. Altair SimSolid Professional reads 3D solids from CAD files directly without requiring assistance from the CAD application.

All mainstream CAD systems are supported including:

  • NX
  • Creo
  • Onshape
  • Inventor
  • Solid Edge

As well as these common neutral formats:

  • STEP
  • VDA
  • JT
  • CGR
  • Parasolid
  • ACIS
  • STL

As always, associative model update is available for design geometry from any CAD source. Change the geometry and all analysis definitions, loads and constraints are automatically reapplied. This makes evaluating design performance variation fast and easy.

Analysis breadth

The vision of Altair SimSolid is to provide advanced analysis packaged simply without all the myriad of settings and tolerances found in other FEA applications. Adaptive analysis replaces manual meshing. Material and geometric nonlinear analysis is done without configuration. All are optimized with parallel processing and run quickly in second to minutes.

Altair SimSolid Standard edition comes with linear static and modal analysis. Our Power edition adds thermal, thermal-stress, material nonlinear and geometric nonlinear. The target with Altair SimSolid Professional edition is to extend our simulation capabilities to support both multi-step and chained analysis solutions.

Multi-step indicates an additional analytic dimension such as load history, time or frequency. This includes analyses such as transient dynamics (our first offering). We also plan frequency and random dynamic response as well as multi-step nonlinear.

Chained analysis means the results from one analysis can be used as inputs to another. This is an integral foundation of the Professional edition. Initially, chained analysis in the Professional edition includes:

  • material nonlinear linked to geometric nonlinear
  • modal linked to transient dynamics

Further additions will include linking for modal to frequency and random response as well as nonlinear static linked to modal for mode stiffening.

Connections and connections automation

Advanced welds connections for spot, laser and fillet welds have been moved to the professional edition. This is complemented with new unique weld creation functions that automate this process on complex assemblies. These will be extended further to provide support for advanced physical conditions such weld shrinkage. More general part based connections that are bonded, sliding, or contain separating contact remain in our other product editions. A full list of product features for all editions can be found here.

Available now

Altair SimSolid Professional is available now. Monthly subscriptions will not be offered. All license sales will be done directly by Altair SimSolid or our regional resellers. Please contact us for more information about this exciting product.
