C++ for scientific computing
I contribute to deal.II, a finite-element library for numerical simulation. My work covers interpolation performance and affine coordinate mapping.
Grid spacing
All contributions ↗delta_x[d]Compute once in the constructor.
Reuse during interpolation.
Cache uniform-grid spacing
Precomputed grid spacing in InterpolatedUniformGridData instead of recalculating it on repeated interpolation calls.
Guard unsupported cell types
Added an assertion to catch non-hypercube cells in the real-to-unit affine approximation.
Improve affine coordinate mapping
Work on real-to-unit cell mapping, including geometry changes and regression tests.
