Multiphysics and coupled numerical simulations are rapidly becoming important as interdisciplinary studies are gaining prominence. My PhD work involves development of numerically and computationally efficient methodologies and software for simulating coupled multi-physics problems.

Tasks : - OpenFoam simulation of centrifugal blowers used in automobile HVAC systems and validation. Simulation process automation for minimal user interaction and remote execution. - Validation the simulation result with experimental values using both MRF(Multiple Reference Frames) and AMI(Arbitrary Moving Inerface). - Feature development in OpenFOAM using C++. Bash scripting.

Performance optimization of graphics engine for visualization of results of Multi Body Simulation. Successfully optimized graphics engine using vertex and video buffers. Improved the performance by 2 fold by redoing parts of visualization using shaders especially Geometry Shaders. The above mentioned work is done for a graphics engine based on OpenGL and the frame work was based in C++ and Java.

Implementing and preparing benchmark cases for the in-house software framework for Tsunami simulations. The framework is called Sierpinski (https://www5.in.tum.de/sierpinski/).

Lecturer for Theoretical subjects :Hydraulic Machinery and Systems,and Basics of Mechanical Engineering. Tutor for Lab Courses of : Hydraulic Machinery, CAD-CAM (This involved analysis using ANSYS Software).

Project Scheduling and planning of machine erection activities in coordination with Civil construction work. Preparing material requirement estimates and cost estimates in accordance with the scheduling done and by reading the machine drawings and fabrication drawings provided by client/manufacturer. Preparing reconciliation reports and project progress summery. Erection of equipment like conveyors, and structure or holding hoods and chutes for Raw mill Hoppers in a cement plant.

Performing Multiphysics and coupled numerical simulations is rapidly becoming important as interdisciplinary studies are gaining prominence. in my PhD I am working to develop numerically and computationally efficient methodologies to perform such coupled simulations.
