Coreform | Introducing Coreform IGA for Abaqus - Empowering Meshing-free Workflows for Abaqus Simulations

We were honored to have Greg Vernon from Coreform present at the 2026 SIMULIA Americas Users Conference in Novi, Michigan, May 13-14, 2026.

Abstract: 

Coreform IGA for Abaqus brings meshing free, CAD exact isogeometric analysis (IGA) to the Abaqus ecosystem. Built on Coreform’s Flex Representation Method, it enables Abaqus users to run analysis directly on CAD geometry, cutting the time typically spent creating, repairing, and validating finite element meshes.

We will walk through the user workflow integrated into Abaqus/CAE, from CAD import and trimming aware model setup through job submission to Abaqus/Standard and post processing in familiar Abaqus tools. We give an intuitive explanation of two enabling concepts: Bézier extraction, which makes spline bases (IGA bases) compatible with standard finite element assembly and integration, and trimming which preserves exact CAD boundaries and small features without mesh induced distortion.
Attendees will see how spline-based discretization's deliver smooth solution fields, accurate stresses, and rapid convergence per degree of freedom—often reducing the need for extensive mesh convergence studies. Benchmark and industrial examples will compare accuracy and turnaround time against conventional FE models while leveraging existing Abaqus capabilities such as material models, analysis procedures, loads, boundary conditions, and output requests.

We conclude with current product capabilities, recommended use cases, and a forward look at planned extensions, positioning Coreform IGA for Abaqus as a practical step toward CAD to analysis workflows for everyday Abaqus simulations.

Greg Vernon

Director of Product - Coreform

Greg has a Bachelor’s degree in Aeronautical and Mechanical Engineering from RPI and a Master’s degree in civil engineering from Brigham Young University.  After receiving his Bachelor's degree, he worked as a finite element analysis specialist at the US Dept of Energy's Kansas City National Security Campus managed by Honeywell, where he was an avid user of Abaqus (CAE and solvers) and government simulation tools. While at Honeywell, Greg led several R&D projects investigating isogeometric analysis (IGA) which eventually led him to join Coreform in 2020 as the Director of Product where he leads efforts to commercialize IGA and uses IGA to solve challenging engineering problems for Coreform's customers.  Greg is excited to see isogeometric analysis come full-circle with its integration into Abaqus and is eager to share this presentation on Coreform IGA for Abaqus with all of you.
