yt.frontends.amrvac.io module¶

AMRVAC-specific IO functions

class yt.frontends.amrvac.io.AMRVACIOHandler(ds)[source]¶

Bases: BaseIOHandler

io_iter(chunks, fields: list[tuple[str, str]])¶

peek(grid, field)¶

preload(chunk, fields: list[tuple[str, str]], max_size)¶

push(grid, field, data)¶

yt.frontends.amrvac.io.read_amrvac_namelist(parfiles)[source]¶

Read one or more parfiles, and return a unified f90nml.Namelist object.

This function replicates the patching logic of MPI-AMRVAC where redundant parameters only retain last-in-line values, with the exception of &filelist:base_filename, which is accumulated. When passed a single file, this function acts as a mere wrapper of f90nml.read().

Parameters:: parfiles (str, os.Pathlike, byte, or an iterable returning those types) – A file path, or a list of file paths to MPI-AMRVAC configuration parfiles.
Returns:: unified_namelist – A single namelist object. The class inherits from ordereddict.
Return type:: f90nml.Namelist
