Master Thesis Student: At University of Berlin, I developed and implemented a viscoelastic fluid model in OpenFOAM's C++ codebase to simulate free-rising bubbles. Modified the bubbleInterTrackFoam solver by implementing an extra stress tensor and adapting the viscoelasticModel library. Performed pseudo-2D and 3D simulations to validate the implementation and optimize numerical parameters. I created visualizations and graphs with Python.
