Key Highlights
- FEAST 2025, an indigenous finite‑element suite, was launched at NAFED08 hosted by IIT Hyderabad.
- The tool now serves major programmes such as Gaganyaan, the proposed Indian space station, and the Next Generation Launch Vehicle.
- Four‑thousand+ licences spanning academic, SME and enterprise tiers have already been distributed, with Windows‑ and Linux‑compatible builds and a free trial.
- ISRO released a pedagogical textbook on finite‑element methods and announced a forthcoming CFD package named Pravaha.
Detailed Insights
During the 8th National Finite Element Developers’/FEAST Users’ Meet, ISRO’s Vikram Sarabhai Space Centre (VSSC) showcased FEAST 2025, the latest iteration of its home‑grown finite‑element analysis (FEA) environment. The software emulates the response of structures under mechanical loads, thermal gradients and dynamic excitations, thereby replacing the need for expensive overseas licences in Indian research and industry. By offering three distinct editions—Academic, Premium and Professional—FEAST addresses the requirements of university curricula, small‑ and medium‑scale manufacturers, and large‑scale aerospace contractors alike. Compatibility with modest hardware on both Windows and Linux platforms further widens its reach.
Strategically, FEAST underpins the structural design workflow for several flagship missions. In the crewed Gaganyaan programme, it validates load paths of the crew module; for the envisioned Bharatiya Antariksh Station, it assists in assessing truss and habitat integrity; and within the Next Generation Launch Vehicle (NGLV) project, it optimises the launch‑vehicle airframe for weight and strength. The broad adoption underscores ISRO’s commitment to self‑reliance in critical engineering tools.
Beyond software, ISRO is bolstering user competence through a comprehensive guide titled “Introduction to Finite Element Analysis,” authored by experts from VSSC and the Liquid Propulsion Systems Centre (LPSC) and edited by Dr. S. Somanath and Dr. S. Unnikrishnan Nair. The volume provides step‑by‑step tutorials, solved case studies, and practical tips for leveraging FEAST in real‑world projects.
Looking ahead, VSSC Director Dr. S. Unnikrishnan Nair announced “Pravaha,” an indigenous computational fluid dynamics (CFD) platform intended to complement FEAST and expand ISRO’s simulation capabilities across fluid‑flow domains.
