Publication in CMAME

5th publication from our ‘adaptive isogeometric topology optimization’ project is now online in CMAME. What’s interesting and a matter of pride is that we have a 100% acceptance rate in this project. None of the papers have been rejected and got exactly published at our first preferred journal itself. We thank the editors of seeing the quality in our work and the anonymous reviewers for seeing the value in our submitted drafts and strengthening it with constructive suggestions and comments.

So far we had been working with the SIMP methodology of topology optimization. This time, we tested the versatility of our framework by implementing the reaction-diffusion equation based topology optimization methodology. We combined RDE-TO, Multi-patch NURBS, Adaptive mesh refinement and the GIFT framework in our unified methodology and tested it on 2D and 3D geometries, with excellent optimized topologies and remarkable computational speedup.

July 2025

18th U.S National Congress on Computational Mechanics

I had the opportunity to present two my research on at the 18th U.S. National Congress on Computational Mechanics, held in Chicago from July 20-24, 2025.

First, I gave an oral presentation on the efficiency of PHT-Splines in structural topology optimization of plane, 3D, plates and shell structures. Next, I presented my poster on the practical implication of multi-patch isogeometric analysis to integrate the sketch to structure part of an engineering design environment.

Had the opportunity to interact with a lot of researchers and industry people working in structural mechanics.


May 2025

16th World Congress on Structural and Multidisciplinary Optimization

I had the opportunity to present my research at the 16th World Congress on Structural and Multidisciplinary Optimization (WCSMO 2025), held in Kobe, Japan from May 18-23, 2025. Had the opportunity to meet Dr. Ole Sigmund again and also many other pinoeers of structural optimization.

Publication in Engineering with Computers

Published our latest paper on isogeometric topology optimization. This was our fourth (and sort of final) paper on the work that our team (me, Abhinav, Bhagath, and Prof. Rajib) has been working on for the past many years (Read the history of the project here), where we combined density based topology optimization, multi-patch CAD geometries, adaptive isogeometric analysis using PHT-Splines and structural mechanics (2D, 3D, plates, and shells).

The paper proposes a generalized framework towards continuity and effciency for optimial design using multi-patch IGA.

National Finite Element Developer's meet

I had the opportunity to present my research and proposal at the National Finite Element Developer’s meet (NAFED 2025) held at IIT Hyderabad. This was organized by the VSSC center of Indian Space Research Organization (ISRO), as part of advancing and promoting FEAST - their structural analysis software. My presentation was on a proposal on how to implement an Isogeometric analysis (IGA) module on FEAST.


December 2024

1st International and 7th National Conference on Multidisciplinary Design, Analysis and Optimization

1st International and 7th National Conference on Multidisciplinary Design, Analysis and Optimization (iNCMDAO 2024), held Indian Institute of Science (IISc), Bengaluru, from December 16 – 18, 2024. My paper dealt with inverse material design on generating the geometry of auxetic metamaterials (materials with negative Poisson’s ratio) using structural topology optimization. Had the opportunity to meet and interact with Dr. Ole Sigmund, the pioneer of topology optimization.
