There are several other software packages that provide isogeometric analysis capabilities besides LS-DYNA. Some of these include:
Abaqus: Abaqus offers isogeometric analysis as part of its SIMULIA suite of products. It supports the use of NURBS-based geometries and provides several options for the integration of NURBS and finite element analysis.
ANSYS: ANSYS offers isogeometric analysis capabilities through its Workbench platform, which includes a dedicated isogeometric analysis tool called ANSYS AIM. This tool provides a streamlined workflow for creating and analyzing NURBS-based geometries.
Kratos: Kratos is an open-source finite element software package that includes support for isogeometric analysis. It provides a range of NURBS-based shape functions and supports several integration schemes.
NURBS-Python: NURBS-Python is a Python library for NURBS-based geometric modeling and analysis. It provides a range of tools for creating and manipulating NURBS-based geometries, and supports several finite element analysis packages.
FEniCS: FEniCS is another open-source finite element software package that includes support for isogeometric analysis. It provides a range of NURBS-based shape functions and supports several integration schemes.
GeoPDEs: GeoPDEs is a Python library for the numerical solution of partial differential equations on NURBS-based geometries. It provides several tools for the analysis of NURBS-based geometries, including isogeometric analysis capabilities.
These are just a few examples of the software packages that provide isogeometric analysis capabilities. There are many other packages available, each with their own strengths and weaknesses. The choice of software will depend on the specific requirements of your analysis, as well as your familiarity with the software and its capabilities.
