Adaptive wavelet schemes and finite volumes

We consider a procedure for combining high order finite volumes and tree-based nonuniform grids. Especially, we focus on efficient algorithms for third order multidimensional volume interpolation and communication between levels of refinement. In the end, numerical results are reviewed to validate our approach

AMR code

The present code is a small self-sufficient program for the AMR simulation presented in the paper "A multigrid AMR algorithm for the study of magnetic reconnection" It is just one long script with inclusions, starting from struct.c and ending with mhd.c or arb2plot.c, so struct.c C opert.c C derive.c C wav.c C multigrid1.c C mhd.c struct.c C opert.c C derive.c C wav.c C multigrid1.c C arb2plot.c To compile it with Linux, type "gcc -fopenmp -o mhd mhd.c -lm" in the folder where the files are "./mhd" or "./mhd >out.txt&" to execute The parameters may be changed at the beginning of the "mhd.c" program If you need any information or advice you can send a message to: [email protected]
