From e130e57efcee4fb08cae9a5888c67c83db63abb4 Mon Sep 17 00:00:00 2001 From: Phil Miller Date: Mon, 30 Aug 2021 16:26:55 -0400 Subject: Make buffer of scraped particles available to Python code (#2164) * Added wrapper to get number of particle species tracked by the scraper Not sure if this is going to be useful, but it demonstrates a method to get information from the ParticleBoundaryBuffer into Python. * Stubbed out the main wrapper functions * Added parameters to wrapper * Added wrapper for getting the number of particles scraped of a species on a boundary * added picmi arguments to scrape particles at the domain boundary * Added wrapper to get the full particle buffer into python * rearanged the getBuffer properties code a little * Added docstrings +other suggested changes * Added num_particles_impacted_boundary docstring * fixed mistake in docstring * Changed boundary parameter to be a string for clarity * Fixed issue with the boundary parameter for scraping * Fixed issue with the boundary input for scraping stats wrapper * Added demonstration of particle scraping wrapper * Added analysis.py file * Fix typo in one of the dimension maps Co-authored-by: Roelof Groenewald <40245517+roelof-groenewald@users.noreply.github.com> * Added before esolve to warpx evolve * added test for the scraped particle buffer wrappers * Moved python PICMI particle boundary scrape test * Renamed test file to the correct name * Removed old test * added special functionality to get the timestep at which particles were scraped * removed debug print * added python wrapper for the clearParticles() function of the scraper buffer * added special wrapper function to get the timesteps at which the particles in the boundary buffer were scraped * updated test to match the non-PICMI test for the particle scraper buffer * Fix uncaught rebase mistake * re-activated picmi test of accessing the scraped particle buffers via python * added documentation for the new parameters involved in the scraped particle buffer and fixed remaining issue with picmi test * changes requested during code review Co-authored-by: mkieburtz Co-authored-by: Roelof Co-authored-by: Roelof Groenewald <40245517+roelof-groenewald@users.noreply.github.com> --- Source/Python/WarpXWrappers.h | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'Source/Python/WarpXWrappers.h') diff --git a/Source/Python/WarpXWrappers.h b/Source/Python/WarpXWrappers.h index 53d461e65..71eb5b4fd 100644 --- a/Source/Python/WarpXWrappers.h +++ b/Source/Python/WarpXWrappers.h @@ -104,6 +104,18 @@ extern "C" { void warpx_addRealComp( const char* char_species_name, const char* char_comp_name, bool comm); + int warpx_getParticleBoundaryBufferSize(const char* species_name, int boundary); + + int** warpx_getParticleBoundaryBufferScrapedSteps( + const char* species_name, int boundary, int lev, + int* num_tiles, int** particles_per_tile); + + amrex::ParticleReal** warpx_getParticleBoundaryBuffer( + const char* species_name, int boundary, int lev, + int* num_tiles, int** particles_per_tile, const char* comp_name); + + void warpx_clearParticleBoundaryBuffer (); + void warpx_ComputeDt (); void warpx_MoveWindow (int step, bool move_j); -- cgit v1.2.3
