Frequently Asked Questions

What does SIMULIA Suite include?

SIMULIA Suite versions 2022–2024 include four components: Abaqus (FEA solver and CAE environment), Tosca (structural optimization), fe-safe (fatigue and durability analysis), and Isight (process automation and multi-disciplinary optimization). The 2020 and 2021 versions in this store include Abaqus only.

What is the difference between Abaqus Standard and Abaqus Explicit?

Abaqus Standard uses implicit time integration for static and low-frequency dynamic analysis — it delivers high accuracy for equilibrium problems including contact, buckling, and nonlinear material response. Abaqus Explicit uses explicit time integration for high-speed transient events such as crash, impact, and drop testing, where inertia effects dominate and convergence of an implicit solver would be impractical.

Does Abaqus require 3DEXPERIENCE or internet access?

No. All versions in this store install and operate fully offline on Windows. The 3DEXPERIENCE platform is not required and is not part of this purchase.

What file formats does Abaqus support?

Abaqus uses its native input format (.inp) for model definition and output database format (.odb) for results. It also imports geometry via STEP and IGES, and links directly to CATIA V5 and SolidWorks models through CAD associativity features.

Can Abaqus open SolidWorks and CATIA files?

Yes. Abaqus/CAE supports direct associativity with SolidWorks and CATIA V5, allowing geometry updates from those CAD tools to propagate into existing Abaqus analysis models while preserving loads, boundary conditions, and mesh seeds.

What is Isight used for?

Isight automates simulation workflows by chaining Abaqus, CAD tools, and external applications into parameterized process flows. It runs Design of Experiments studies, parameter sweeps, and optimization algorithms — executing thousands of design variations automatically to identify optimal parameters without manual intervention.

What is fe-safe used for?

fe-safe calculates fatigue life and durability from Abaqus stress results. It identifies critical failure locations, predicts cycles to crack initiation, and covers multiaxial fatigue in base materials, weld fatigue using the Verity structural stress method, and elastomer fatigue through the fe-safe/Rubber module.

What is the difference between Abaqus and Ansys Mechanical?

Both are general-purpose FEA platforms. Abaqus is widely regarded as the benchmark for nonlinear analysis — particularly rubber, composites, and metal forming — and includes purpose-built explicit dynamics through Abaqus Explicit. Ansys Mechanical covers a broader range of physics in its standard product, with topology optimization built in. SIMULIA Suite adds fatigue (fe-safe) and optimization (Tosca) capabilities that require separate Ansys modules.
