Re: [sparta-users] Time-varying inlet properties

[Steve P. <sj...@gm...>]

A relatively simple way to do this is to redefine the fix emit/face/file
command every N steps,
using an input file with multiple named sections of grid point values.

E.g. do something like this:

fix influx emit/face/file air xlo input.data step0
run 1000
fix influx emit/face/file air xlo input.data step1000
run 1000
fix influx emit/face/file air xlo input.data step2000
run 1000

You can define as many sections in the file (or in different files) as you
like.
Note that redefining a fix with the same ID and style, deletes the old one,
and re-creates the new one.
