Faster Structural Analysis
with ALTAIR SIMSOLID
Altair SimSolid is a groundbreaking simulation technology designed for designers, engineers, and analysts. It eliminates geometry preparation and meshing; the two most time-consuming, expertise-intensive, and error-prone steps in traditional structural simulation.
Unlike traditional methods, SimSolid efficiently analyzes large, complex CAD assemblies without the need for geometric simplification or meshing. Its speed allows engineers to run multiple tests and simulations in the time it would take to complete a single analysis with other FEA software.
By enabling fast and accurate structural analysis directly on a desktop machine, SimSolid accelerates the design process and delivers accurate results in a fraction of the time.

Structural Analysis
of a Marine Jib Crane
A 4-minute Simulation
SimSolid means rapid design iterations – check out this video and see how structural analysis of a marine jib crane is completed in 4 minutes, including contact and bolt tightening analysis input.
SimSolid speeds up design iterations significantly due to:
- Simple and intuitive constraints and analysis setup
2. No geometry preparations
3. No meshing
This analysis would take hours in conventional FEA.
Why Choose Altair SimSolid?
Seamless CAD-to-simulation transition. Go from CAD to simulation quickly, in seconds, using straightforward workflows on full CAD assemblies, with no cleanup required.
Get results in minutes to seconds. While competitors limit your simulation capabilities, SimSolid enhances throughput, enabling concurrent assessments of design scenarios and iterations.
No more meshing. While most platforms get bogged down by time-consuming meshing, SimSolid’s groundbreaking approach eliminates the need for geometry simplification or idealization.
Precision redefined. Don’t compromise with inconsistent outputs. SimSolid guarantees consistent, accurate results, setting the gold standard in simulation.
Complex assemblies? Not a problem. Where others stumble with intricate designs or large assemblies, SimSolid effortlessly handles complex assemblies, giving you reliable results every time.
“When we are ordering tons and tons of the raw materials for our chains. A pound here and a pound there starts becoming important, so that’s where we spend a lot of time trying to optimize our product. Applying SimSolid to this challenge in the long run will make us a lot of money .”

FAQ
Got questions? Here are the ones we hear the most:
What are the requirements for SimSolid?
SimSolid is only supported on the Windows platform. It is recommended to use a Windows 10 OS on an Intel I7 based computer, or similar, with at least 4-cores and 16 GB of memory. For all graphics features to be supported, SimSolid requires an OpenGL graphics card, version 3.1 or higher.
How does SimSolid work?
SimSolid is based on new FEA technology that does not use a mesh, but instead applies classes of higher order functions on both a part and a CAD feature basis. The SimSolid computational engine is based on extension to the theory of external approximations. External approximations are a generalization of Finite Element Method (FEM) in terms that:
- Absolutely arbitrary geometrical shapes can be used as “finite elements”.
- Basis functions which approximate the field of interest in the “element” can be of arbitrary class and are independent of the “element” shape.
- The degrees of freedom are integrals over corresponding geometrical entities.
- Multi-pass adaptive analysis to control the solution accuracy.
Is SimSolid accurate?
Ian Symington of NAFEMS investigated the accuracy of Altair SimSolid through a series of eight analysis benchmarks. Article originally published in Benchmark Magazine by NAFEMS, the International Association for the Engineering Modeling, Analysis & Simulation Community. Find the article here.
