Plotfiles and Other Output

The following inputs must be preceded by “amr” and control frequency and naming of plotfile generation as well as whether the EB geometry should be written out.

	Description	Type	Default
plot_int plot_per_exact plot_per_approx	Frequency of plotfile output; if -1 then no plotfiles will be written at this frequency Time period of plotfile output (exact); will modify dt if -1 then no plotfiles will be written at this frequency Time period of plotfile output (approximate); does not modify dt if -1 then no plotfiles will be written at this frequency	Int Real Real	-1 -1 -1
plotfile_on_restart	Should we write a plotfile when we restart (only used if plot_int>0)	Bool	False
plot_file	Prefix to use for plotfile output	String	plt
write_eb_surface	Should we write out the EB geometry in vtp format 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.

	Description	Type	Default
plotVariables	Space separated list of variable names. Takes precedent 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_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	0
plt_tracer	Save tracer to plot file	Int	0
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_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	Save velocity divergence to plot file	Int	0
plt_vfrac	Save EB volume fraction to plot file	Int	1

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