Nishan J.

CFD & FEA Specialist | PhD Aerospace & Mechanical Engineering

CFD and FEA consultant with post-doctoral research experience and 15+ publications in peer-reviewed journals. I run simulations from CAD cleanup through meshing, solving, and post-processing, and deliver results with clear reports and animations. Can handle complex and multi-disciplinary projects. Applications: - HVAC, ventilation, and indoor air quality - Heat transfer and thermal management (heat exchangers, cold plates, data centers) - Turbomachinery and aerodynamics - Multiphase flow (free-surface, particle-laden, droplet dynamics) - Adjoint-based design optimization (DAFoam, Dakota) - FEA structural and thermal-structural analysis - Far-UVC pathogen modeling and disinfection Interested in and exploring AI/ML integration with CFD workflows (surrogate modeling, physics-informed approaches). Tools: - CFD: OpenFOAM, Ansys Fluent, Basilisk, CONVERGE - FEA: Code_Aster, Calculix, Elmer, Abaqus - CAD/Meshing: Blender, FreeCAD, Gmsh, snappyHexMesh - Post-processing: ParaView, Python, Blender - Programming: Python, C/C++, Fortran, MATLAB I have my own high-performance compute server, so simulations run on my hardware with no cloud costs passed to you.
