I'm wondering: #physics makes a lot of use of #periodic functions, in particular it is very useful to solve space-dependent equations in representative volumes with #periodicBoundaryConditions.

However I've only seen it done with periodicity along orthogonal directions, aligned with a Cartesian frame.

Do you know of work, e.g. #PDE resolution, in nonrectangular #periodicDomains? E.g., in a #tiled hexagon? (but with a sufficiently generic setting, not exploiting regular hexagon symmetries) Even better if the periodicity parameters themselves are among the unknowns.

(Maybe I'm completely missing something obvious there, I'm in my first steps towards defining what I want - any random thought on the topic highly welcome!)

The periodic table for spatial analysis, where each element of the table contains a set of explained spatial analysis tools, grouped by color and vector on the left and raster on the right #periodic

When I was studying #DynamicLoading of a #Structure, at least for the case of small deflections and a single-degree-of-freedom, we covered both #Periodic and #ImpulsiveLoads. The former take place over an extended period and so damping is important, while for the latter, if they are short-lived, then damping can be neglected.

Imagine a circular wheel rolling, without skidding, on a flat, horizontal surface. The #locus of any given point on its #circumference is called a #cycloid. It is a #periodic #curve with #period over the #circle's circumference and has #cusps whenever the point is in contact with the surface (the two sides of the curve are tangentially vertical at that point).

Almost periodic, but not quite.
