v5d_write

Writes compressed data to a Vis5D+ format file.

Prototype

	procedure v5d_write (
		timestep   [1] : integer,  
		varnum     [1] : integer,  
		data [*][*][*] : float     
	)

Arguments

timestep

A scalar timestep number in the range [1...numtimes]

varnum

A scalar variable number in the range [1...numvars] indicating which variable you want to write.

data

A 3-dimensional float array of gridded data values.

Description

v5d_write() writes data to a file in the Vis5D+ format. The data must be a 3D array of grid values where the number of values to write is equal to nr * nc * nl(var), ordered as:

     data[row + nr * (col + nc * lev)]

where row increases from North to South, col(umn) increases from West to East, and lev(el) increases from bottom to top.

The data is written in a compressed format. See the documentation for v5d_create for a discussion of how to best utilize compression settings for your data.

For further information on Vis5D+ and file formats, see documentation at the Vis5D website.
