It was really unique experience and interactive classes which made our learning more fun. I especially liked the error propagation game and as well as another one which is picking up the cheat and drawing the graph on the board and many more games we played which broke all the complex concepts into a very easy and understandable one.
Education Advice
The academic journey requires commitment, consistency, and a holistic approach.
Level 1
Clear goals provide direction, motivation, and a sense of purpose. Begin by defining specific measurable and realistic academic goals. Define short-term goals and long-term goals.
Level 2
Have a consistent study habits that can lead to better retention, understanding and skill development. Work Smartly. Break down larger tasks into smaller and manageable steps. This ensures a consistency of study hours.
Level 3
It helps deeper understanding and make your learning more meaningful. It boosts you to tackle challenges in both your academic and professional life. Don't memorize materials, ask questions, debate, analyze, think beyond the box. Do more exercises from various text books.
Level 4
Academic journely not stops with studies, but you should have a sound health and mental-wellness. Keeping stress away, having balance of the life on academic and health enhances focus and creativity. Ensure study time is balance with relaxation, recreational activities, exercises and healthy eating.
Level 5
Collaborate with fellow students, don't think they are your competitor, instead grow with them and make them to grow, this could help in a long-term relations and future collaboration. Who knows, who will become who. Don't hesitate to seek help when needed. Connect with professors, peers and guides. Participate in study groups, attend workshops, use library and laboratory resources effectively.

I have used FEM for solving bioheat equations in cancer treatment projects. Our research group has also used vector finite element method for microwave ablation cancer treatment. I worked with various projects with NUMA Engineering Services Ltd, Ireland.
I have used the finite volume method for various simulations. I am especially skilled at OpenFOAM, an open-source CFD software that simulates fluid flow and heat transfer with a variety of solvers and utilities. I worked on various projects with NUMA Innovation Limited, UK.
FPM, a generalized finite difference method, deals CFD using a set of discrete points rather than a mesh. It scatters the points to represent the problem domain. I worked with Fraunhofer ITWM and TU Kaiserslautern, Germany to accelerate FPM using GPU accelerators. It was part of my PhD thesis.
This method is based on statistical mechanics and the behavior of fluid particles. It is effective for complex boundary conditions. It is known for its simplicity, parallel computing efficiency. We worked on hyperbolic lattice Boltzmann method for phase change problems.
