Our journey with Isogeometric Analysis (IGA) began with a clear vision — to eliminate the disconnect between design and analysis by unifying CAD and CAE workflows. This philosophy has guided every step we’ve taken, from building foundational IGA tools to advancing adaptive simulation techniques. The timeline below captures key milestones and technical breakthroughs that have shaped our work and mission.
The journey began in 2019 when Abhinav started exploring Isogeometric Analysis (IGA) and PHT-splines, working alongside then-M.Tech student Prashoon. This marked the initial foray into geometry-aware finite element methods at IIT Roorkee.

With new goals in sight, the team introduced the Continuous Density Function (CDF) to produce smooth, printable structures with minimal post-processing. Despite team transitions — Bhagath departed for an internship in Luxembourg and Abhinav completed his Ph.D. — collaborative efforts continued.

Venturing into fourth-order differential equations, the team addressed challenges in C1 continuity for mesh-based methods. Collaborating with Lokanath Barik, developed a novel methodology for topology optimization and local refinement of multi-patch NURBS with fourth-order strong forms.

In 2025, a major milestone was achieved with the development of a user-friendly GUI for IGA, enabling intuitive NURBS modeling, and execution of static and eigenvalue analyses across 2D, 3D, and shell structures. Built in collaboration with Avkalan Labs and ISRO, the interface enhances accessibility to IGA by integrating modeling, analysis, and result visualization in a seamless workflow.
