Ascent

Ascent has been integrated into MFIX-Exa for in situ visualization. MFIX-Exa must be built with Ascent support to use this feature.

The following inputs must be preceded by the prefix output.ascent and control frequency of the Ascent pipeline.

	Description	Type	Default
actions	Name of yaml file of the ascent actions (ex. ascent_actions.yaml). If no file name is provided, then calls to Ascent are skipped.	String
int	Frequency of ascent pipeline in timesteps; -1 to disable ascent pipeline based on timesteps.	Int	-1
per_approx	Time period of the ascent pipeline in simulation time (approximate); -1 to disable ascent pipeline based on simulation time.	Real	-1
on_restart	Run the Ascent pipeline when restarting a run.	Bool	false
fluid.variables	Fluid variables to publish, from the fluid variable names in Plotfiles. Defaults to the historical Ascent field set when unset: eb_volume_fraction, velocity, volume_fraction, temperature, species	Strings	see below

Note

Ascent actions must reference the variable name listed in Plotfiles. For example, velocity components are identified as u_g`, v_g, w_g, phasic fluid volume fraction as ep_g and the geometric volume fraction as volfrac.

Warning

If an Ascent pipeline is being included in a GPU build/run, then you must enable managed memory by setting amrex.the_arena_is_managed = true.
