Having the possibility of enforcing the addition of a axis to a file

[millour]

So far if multiple axes are defined (e.g. axis1, axis2, etc.), but only one is used (e.g.all output fields in file are with axis_ref="axis2"), then it is the only axis written to the file.

Allowing users to specify that alternative axes, although not used, should be included in the output file would be useful.

Maybe by adding a flag output="always" to the axis (or file?) parameters?

Yes, correct.

Why ? Do you have a good reason for this because it will take a lot of new development ?
In fact the connection between file and axis (or domain) is done through the field. A file doesn't know anything about axis that must be wrote only if it is referred by a field.

Maybe by adding a flag output="always" to the axis (or file?) parameters?

In fact, I think that the best way will be to embed axis (or domain or grid) inside a file by the same way as a field.

It is mainly for postprocessing. For instance you declare vertical axes in pressure and altitude, and then switch from one to the other when visualizing the data (assuming the visualisation or post-processing software can do that).

In fact the connection between file and axis (or domain) is done through the field. A file doesn't know anything about axis that must be wrote only if it is referred by a field.

Yes indeed, this is probably the best way to handle it.

Ok, so it will be available in the next branch XIOS_V2, planed in some month (probably September 2014).

I close the ticket because it is very old.
We don't see a simple way to implement this functionality.
Nevertheless, if there is strong (and justified) request the ticket could be reopened.
