Quantas command line
====================

The command reference is generated directly from the public Click application.
Consequently, command names, option types, accepted choices, defaults, option
groups, and long-form help are version-matched to the installed Quantas source.
The surrounding pages add workflow context without copying the parser
specification by hand.

Start by selecting a scientific group:

.. code-block:: console

   quantas ha --help
   quantas qha --help
   quantas elasticity --help
   quantas seismic --help
   quantas eos --help
   quantas thermoelasticity --help

Most calculations follow ``run -> inspect/plot/export``.  EOS uses a persistent
record archive because one dataset commonly produces several candidate fits;
Thermoelasticity separates calibration from point, grid, and profile analysis.
Those differences are explained in the corresponding module pages.

Before using the generated option lists, read :doc:`conventions` for range
syntax, repeatable options, units, reports, overwrite behavior, plotting
presets, and exit statuses.
