The event Hands on Training in Modeling Fluid Flow Problems HTMF-2025 (HTMF-4.0) is set to be the continuation of previous successful FDPs HTMF 1.0, HTMF 2.0, and HTMF 3.0, which were held at the Department of Mathematics, School of Advanced Sciences, Vellore Institute of Technology, Vellore. The platform is created to facilitate training, consultancy, and research in the domain of fluid dynamics. HTMF focuses on hands-on experience in solving complex fluid dynamics problems with the support of experts in the domain. During this five-day program, participants will explore a diverse range of topics, starting from the Basics of fluid dynamics, Adomian decomposition Method (ADM), Spectral methods, and Finite Element Methods (FEM) in tackling PDEs related to the fluid flow problem.
