.. _physics-accretionHaloTotal:

Halo Total Accretion Rates
==========================

Class providing total accretion rates onto halos, i.e. the mass which would be accreted in a dark matter-only universe.

**Default implementation:** ``accretionHaloTotalSimple``

Methods
-------

``accretionRate`` → ``double precision``
   Return the total baryonic plus dark matter accretion rate (in :math:`\mathrm{M}_\odot` Gyr\ :math:`^{-1}`) onto the halo corresponding to the given ``node``, i.e. the mass which would be accreted in a dark matter-only universe scaled to the total mass.

   * ``type(treeNode), intent(inout) :: node``

``accretedMass`` → ``double precision``
   Return the cumulative total accreted mass (in :math:`\mathrm{M}_\odot`) in the halo corresponding to the given ``node``, representing all mass accreted over the halo's history.

   * ``type(treeNode), intent(inout) :: node``

.. _physics-accretionHaloTotalBertschinger:

``accretionHaloTotalBertschinger``
----------------------------------

A halo total accretion class that assumes that the accretion rate is equal to the growth rate of the basic component Bertschinger mass property.

.. _physics-accretionHaloTotalSimple:

``accretionHaloTotalSimple``
----------------------------

A halo total accretion class which assumes that the accretion rate equals the growth rate of the basic mass.

**(Default implementation)**
