Coreform Flex is now Coreform IGA. Same technology. Clearer name. Broader platform.
CAD-Based Simulation Without Meshing
Coreform IGA is next-generation isogeometric analysis software for accurate nonlinear simulation directly on CAD — no defeaturing or meshing required.
Coreform IGA
Simulation without compromise
Coreform IGA is next-generation isogeometric analysis software that automates simulation model-building and delivers accurate nonlinear results directly on full-fidelity CAD geometry — without defeaturing, midsurfacing, or manual meshing.
By replacing traditional meshing with spline-based analysis, Coreform IGA helps engineers get trustworthy results hours or weeks faster than conventional FEA workflows.

and analysis process
The Problem with Traditional FEA
Traditional FEA often slows engineers down before the analysis even begins.
The real bottleneck is not solving the model. It is preparing geometry for simulation. Engineers must spend time defeaturing CAD, creating and repairing meshes, and repeating that work with every design iteration. For complex or nonlinear problems, meshing can become especially fragile and time-consuming.
That effort does not improve the product. It is simply overhead required to make the model usable for analysis.
Coreform IGA removes that bottleneck with a meshing-free workflow, helping engineers get to reliable results faster.
What Is Coreform IGA?
Coreform IGA is a CAD-based finite element analysis (FEA) platform built on isogeometric analysis (IGA).
Instead of approximating geometry with low-order finite elements, Coreform IGA:
The result is robust nonlinear simulation on complex geometry.
Two Ways to Use Coreform IGA
Coreform IGA for Abaqus
A push-button alternative to meshing inside Dassault Systèmes’ SIMULIA Abaqus/CAE preprocessor.
Coreform IGA for Abaqus integrates Coreform’s IGA technology directly into Abaqus/CAE workflows, replacing the most time-consuming step in simulation: mesh creation.
Engineers can:
- Run Abaqus simulations directly on CAD geometry
- Eliminate manual meshing while staying inside Abaqus/CAE
- Combine spline-based accuracy with the Abaqus/Standard solver
This solution extends Abaqus workflows, it does not replace them, and introduces a new alternative to defeaturing and meshing within Dassault Systèmes SIMULIA software. No disruption. No retraining. Just faster, more reliable model creation.
Coreform IGA
We’re developing a native isogeometric analysis FEA solver that simplifies model-setup without compromising capabilities or accuracy.
While this solver is currently in the early stages of development, we’ve successfully demonstrated its ability to solve highly nonlinear physics involving static and dynamic behaviors including large deformation, incompressible elasticity, plasticity, and contact, with a variety of explicit and implicit solution methods.
Ideal for:
-
- Nonlinear structural problems of complex single parts or small assemblies
- AI-driven simulation and training-data generation
- Advanced research and development
- Integration into your organization’s CAD-based engineering software

Key capabilities
CAD-Based FEA
- Simulate directly on fully featured CAD geometry
- No defeaturing, midsurfacing, or geometry simplification required
- Works on thin-walled, complex, and highly detailed parts
Faster, More Reliable Results
- Accurate nonlinear results faster than traditional meshing
- More robust and accurate per degree of freedom than FEA
- Easier to use than hex meshing; more reliable than tet meshing
Built for Nonlinear Simulation
- Static and dynamic analysis
- Large deformation and contact
- Complex assemblies and production-scale parts
Legacy FEA solvers require time-consuming mesh generation for every simulation.
Coreform IGA was designed to perform nonlinear simulations directly on CAD, using smooth, high-order spline basis functions that enable engineers to efficiently calibrate simulation accuracy and speed to match any stage of the product development process. Defeaturing is now optional.
Coreform IGA is mathematically proven to be more accurate and robust per degree of freedom than traditional finite element methods.
By leveraging smooth spline basis functions instead of low-order elements, Coreform IGA enables higher-quality solutions with fewer degrees of freedom — particularly for nonlinear problems involving contact, large deformation, and complex geometry
Integrating IGA into Honda’s production process within the next 18 months is a priority for us, especially in the application of aluminum die cast parts, where our current technology takes too long for both setup and simulation. … We are very interested in Coreform’s potential approach to the simulation of aluminum die cast parts.
