Plotfiles and Other Output

The following inputs must be preceded by “amr” and control frequency and naming of plotfile generation.

	Description	Type	Default
plot_int	Frequency of plotfile output; if -1 then no plotfiles will be written at this frequency	Int	-1
plot_per_exact	Time period of plotfile output (exact); will modify dt if -1 then no plotfiles will be written at this frequency	Real	-1
plot_per_approx	Time period of plotfile output (approximate); does not modify dt if -1 then no plotfiles will be written at this frequency. Only one of plot_int, plot_per_exact and plot_per_approx may be > 0	Real	-1
plotfile_on_restart	Should we write a plotfile when we restart	Bool	False
plot_file	Prefix to use for plotfile output	String	plt

The following input must be preceded by “incflo” and controls whether the EB geometry is written out.

	Description	Type	Default
write_eb_surface	Should we write out the EB geometry in vtp format (3D EB builds only) If true, it will only be written once, after initialization or restart.	Bool	False

The following inputs must be preceded by “amr” and control what variables will be written in plotfiles. By default, incflo plotfiles contain the velocity, pressure gradient, density, tracer, velocity magnitude, vorticity, and if using EB, volume fraction. With incflo.use_divu_source = 1 they also contain divu_source, the source \(S\) in the divergence constraint \(\nabla \cdot U = S\).

	Description	Type	Default
plotVariables	Space separated list of variable names. Takes precedence over all other plotfile options. Plotfile will contain only this list, e.g. “amr.plotVariables = velx density” will result in plotfiles containing only the x-component of the velocity and the density.	String	see above
plt_ccse_regtest	Collection of variables for regression test plotfiles (will get overwritten by plotVariables or plt_* flags)	Int	0
plt_*	The plt_* flags below are deprecated in favor of plotVariables. Each one adds (1) or removes (0) one variable from the default list.	Int
plt_velx	Save x-velocity to plot file	Int	1
plt_vely	Save y-velocity to plot file	Int	1
plt_velz	Save z-velocity to plot file	Int	1
plt_p	Save pressure to plot file	Int	0
plt_rho	Save density to plot file	Int	1
plt_tracer	Save tracer to plot file	Int	1
plt_eta	Save viscosity to plot file	Int	0
plt_gpx	Save dp/dx to plot file	Int	1
plt_gpy	Save dp/dy to plot file	Int	1
plt_gpz	Save dp/dz to plot file	Int	1
plt_magvel	Save velocity magnitude to plot file	Int	1
plt_vort	Save vorticity to plot file	Int	1
plt_forcing	Save forcing term for velocity to plot file	Int	0
plt_strainrate	Save strain rate to plot file	Int	0
plt_divu	Not implemented: requesting divu is refused when the inputs are read	Int	0
plt_vfrac	Save EB volume fraction to plot file (EB builds only)	Int	1

If incflo.use_temperature = 1, the temperature is also added to the default list of plotfile variables.

incflo provides the option to write a user defined selection of variables to a “smallplotfile” at an interval that is different than that of the full plotfile. The following inputs must be preceded by “amr” and control frequency and naming of smallplotfile generation.

	Description	Type	Default
smallplot_int	Frequency of smallplotfile output; if -1 then no smallplotfiles will be written at this frequency	Int	-1
smallplot_per_approx	Time period of smallplotfile output (approximate); does not modify dt if -1 then no smallplotfiles will be written at this frequency. Only one of smallplot_int and smallplot_per_approx may be > 0	Real	-1
smallplotfile_on_restart	Write smallplotfile when restarting	Bool	False
smallplot_file	Prefix to use for smallplotfile output	String	smallplt
smallplotVariables	Space separated list of variable names.	String	none
