SimSolid Software for Fast CAD-Based Structural Simulation
Analyze designs faster and iterate more without complex meshing workflows.
Meshless Simulation
What is Altair SimSolid?
Run structural analysis directly on CAD geometry, no meshing, no simplification.
Altair SimSolid is a meshless structural analysis tool that enables engineers to simulate directly on original CAD assemblies, including large and complex models. By eliminating meshing and geometry simplification, teams can focus on loads, connections, materials, and design decisions instead of time-consuming preprocessing. SimSolid is ideal for fast design iteration, helping engineers obtain accurate results quickly and accelerate product development.
Key Features of Altair SimSolid
Fast, meshless structural simulation directly on full CAD assemblies.
Built for Large Assemblies and Real CAD Conditions
SimSolid is designed to handle complex parts and large assemblies, including imperfect CAD with gaps, overlaps, and rough contact surfaces. This allows engineers to work with real-world geometry without time-consuming cleanup or simplification.
Meshless Analysis, No Meshing, No Simplification
Altair SimSolid eliminates the need for geometry simplification and meshing. The original CAD model becomes the simulation model, enabling faster workflows and removing one of the biggest bottlenecks in traditional FEA processes.
High-Fidelity Results and Instant Design Comparisons
SimSolid delivers accurate structural analysis results in seconds to minutes on standard hardware. Engineers can quickly evaluate multiple design scenarios, compare results, and make faster, data-driven decisions.
