CAD-based simulation without meshing
Relative time costs of the model generation
and analysis process
The problem with traditional FEA
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 for Abaqus?
Coreform IGA for Abaqus is advanced isogeometric analysis software that eliminates the tedious manual meshing step required for accurate simulations. Coreform’s workflow starts with a CAD part, immerses it in a high-order spline mesh, and performs a fully automated volumetric trimming operation that produces a new trimmed spline mesh, which can be used for linear and non-linear, static and dynamic simulations.
Instead of approximating geometry with low-order finite elements, Coreform IGA for Abaqus allows you to:
The result is robust nonlinear simulation on complex geometry.
Integrated isogeometric analysis
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.
Who uses Coreform IGA for Abaqus?

- Expert analysts who demand nonlinear fidelity grounded in decades of IGA research
Coreform IGA for Abaqus scales from early design insight to production-grade analysis.
Typical workflows
Coreform IGA for Abaqus simulation technology enables:
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 for Abaqus 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 for Abaqus 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 for Abaqus enables higher-quality solutions with fewer degrees of freedom, particularly for nonlinear problems involving contact, large deformation, and complex geometry.
