What Is Altair SimSolid?

Altair SimSolid is structural analysis software for rapid design validation of complete CAD assemblies. It performs finite element analysis directly on imported CAD geometry — without meshing — and calculates stresses, displacements, strains, natural frequencies, and thermal response for complex parts and large assemblies.

SimSolid is designed for engineers and product developers who need reliable structural results early in the design process, without the geometry simplification and meshing overhead required by traditional FEA tools.

How Does Meshless FEA Work?

Traditional FEA requires converting CAD geometry into a mesh — a process that can take hours for complex assemblies and demands expert knowledge to produce accurate results. SimSolid eliminates this step entirely. It applies adaptive solution functions directly to the original CAD geometry, automatically refining accuracy through multiple solution passes without any user-controlled meshing. The result is structural analysis that runs in seconds to minutes on standard desktop hardware, even for assemblies with imprecise geometry, thin walls, or complex contact interfaces.

Who Is SimSolid For?

SimSolid targets three primary user groups:

• Design engineers who need fast stress and displacement validation during product development without waiting for dedicated FEA specialists
• Simulation analysts working with large assemblies where traditional meshing workflows are prohibitively slow
• Manufacturing and industrial engineers validating welded frames, fixtures, and structural components where geometry is inherently imprecise

Is Altair SimSolid Still Being Developed?

The versions available in this store include 2025.0 and 2026.0.1, indicating active development through at least 2026. Both versions are available for purchase as full offline installations.

Does Altair SimSolid Require HyperWorks or HyperMesh?

No. Altair SimSolid is a fully standalone application. It does not require Altair HyperWorks, HyperMesh, or any other Altair product to install or run. SimSolid operates as an independent desktop application with its own CAD import, analysis engine, and results viewer.

Altair SimSolid Key Features

Core Analysis Capabilities

Meshless FEA Technology

Performs structural analysis directly on CAD geometry without generating a mesh. Eliminates the primary bottleneck of traditional FEA workflows — geometry cleanup and mesh generation — making structural simulation accessible on desktop hardware for assemblies of any complexity.

Adaptive Solution Refinement

Applies multi-pass adaptive analysis that automatically controls solution accuracy. Each refinement pass locally enriches solution functions where needed, converging to reliable results without manual mesh seeding or error-prone convergence controls.

Linear and Nonlinear Statics

Calculates stress, displacement, and strain under static loads. Supports both material nonlinearity (elastoplastic behavior with stress-strain curves) and geometric nonlinearity for identifying failure modes and design limits under realistic loading conditions.

Modal and Dynamic Response

Determines natural frequencies, mode shapes, and frequency response functions. Evaluates vibration characteristics and dynamic behavior for assemblies where resonance and dynamic loading are design-critical factors.

Thermal-Stress Coupling

Simulates temperature distributions across assemblies and calculates resulting thermal stresses. Assesses design performance under thermal loading without requiring a separate thermal solver or model preparation.

Assembly and Geometry Handling

Complete Assembly Analysis

Imports and analyzes fully featured CAD assemblies with automatic part recognition and connection detection. Handles imprecise geometry — gaps, overlaps, and inconsistent tolerances — that would require extensive cleanup in traditional FEA tools.

Advanced Connection Types

Supports bonded, sliding, and separating contact with friction. Dedicated connection elements include bolts with preload, spot welds, rivets, and virtual connectors for accurate assembly-level behavior without simplifying joint geometry.

Loads and Boundary Conditions

SimSolid supports a comprehensive range of load types for accurate boundary condition definition:

• Forces and pressures
• Gravity and inertia relief
• Bolt preload
• Thermal loads
• Hydrostatic and bearing loads
• Remote loads and enforced displacements

CAD Import and File Format Support

SimSolid imports native CAD files directly without requiring the source application to be installed:

• CATIA V4 and V5 (.CATPart, .CATProduct)
• Siemens NX (.prt)
• PTC Creo / Pro/ENGINEER (.prt, .asm)
• SolidWorks (.sldprt, .sldasm)
• Autodesk Inventor (.ipt, .iam)
• STEP (.stp, .step)
• ACIS (.sat)
• Parasolid (.x_t, .x_b)

Results and Visualization

Results are presented through contour plots of stress, displacement, and strain; deformed shape animations; XY plots of response versus frequency; and safety factor evaluations. Model and results views are synchronized for interactive exploration of analysis outcomes across design variants.
