IGA is now supported in some commercial software, like LS-DYNA. The standard FEA approach is used, but the faceted linear basis is replaced with a smooth IGA basis and exact geometry. Coreform Prep is a new preprocessor that will take your existing meshed geometry and convert it to a smooth model that can be exported for use in LS-DYNA. Coreform Prep is currently in development. Contact us if you are interested in this product and we will notify you when the beta portal is ready. This is a first step towards getting the power of IGA into your workflow.
Are you interested in IGA but don’t see it supported by your commercial FEA software yet? Contact us and we can discuss how we can enhance other existing FEA codes to handle IGA.
