Hot and cold plumes in Rayleigh–Bénard convection on an adaptively refined mesh, computed with MicroFE.jl: tools/plumes.jl
Mechanical engineer by training, working in computational mechanics
research at Hochschule Düsseldorf — mostly on unfitted finite element
methods, multi-level hp refinement and immersed boundaries, and the
software that goes with them.
Projects
Unfitted.jl (Julia): unfitted multi-level hp refinement on Cartesian grids with finite-cell immersed-boundary integration.
FoamGen.jl (Julia): open-cell foam geometries for finite element and immersed-boundary tests.
Oritone (theme): a color theme and scientific colormaps for editors, terminals and visualization, after Okabe & Ito.
Oritone LaTeX (LaTeX): document classes and a Beamer theme for theses, manuscripts, CVs and slides.
