What simple methods are there for adaptively sampling a 2D function?
I have a two-dimensional function $f(x,y)$ whose values I would like to sample. The function is very expensive to compute and it has a complex shape, so I need to find a way to get the most information about its shape using the least number of…

Grid rearrangement for anisotropic transport simulations
In computational plasma physics, one often faces problems with extremely high transport anisotropy, 1e6 and more, since transport along the magnetic field is much faster than across. To deal with this in numerical simulations, the common practice is…

simple example of an adaptive mesh refinement code
I have been writing an adaptive mesh refinement (amr) code. As a prototype for the code, I have been looking at an adaptive mesh refinement code written by my adviser (written in c). I find looking at their code to be useful, but the code also does…

Data structures of AMR(Adaptive Mesh Refinement) with quadtree
I am graduate student and recently tried to implement quad-tree based AMR. Well I have implemented simple Poisson Solver on node-based quadtree, but I am not sure that my data structure is right. To be honest, I am not sure about my coding skills.…
