Functions
str	picurv_cli.picgrid.format_picgrid_coordinate (float value)
	Format a coordinate with round-trip-safe binary64 precision.
	picurv_cli.picgrid.content_lines (stream)
	Yield the content lines of a PICurv text payload, skipping blank and # lines.
list	picurv_cli.picgrid.read_picgrid_header (lines, str path, int expected_nblk=None)
	Consume a PICGRID header from a content-line iterator.
list	picurv_cli.picgrid.read_picgrid_dimensions (str path, int expected_nblk=None)
	Read only the header of a PICGRID file.
tuple	picurv_cli.picgrid.parse_coordinate_row (int lineno, str line, str path)
	Parse one coordinate row into three finite floats.
list	picurv_cli.picgrid.read_picgrid_blocks (str path, int expected_nblk=None)
	Read every block of a PICGRID file as node-coordinate arrays.

Variables

Detailed Description

The canonical PICGRID text grid format: its coordinate precision, header reader and coordinate reader, shared by the conductor and the generators.

Not a command. core.py, grid.gen, ic.gen, profile.gen, reduce.gen and spectra.gen import it from picurv_cli/, as they import petsc_binary.py. A PICGRID file is the token PICGRID, a block count, one IM JM KM node-count row per block, then every block's node coordinates in block order, one x y z row per node with i fastest, then j, then k. Blank lines and lines beginning with # are not part of the content.
