## SYNOPSIS

**splash** *file1 file2 file3*...

## DESCRIPTION

SPLASH: A visualisation tool for SPH data (c)2004-2025 Daniel Price and contributors v3.11.2 \[4th April 2025\]

Usage with flags: splash \[-f format\] \[-p fileprefix\] \[-ev\]

-

  \[-x col\] \[-y col\] \[-r col\] \[-cont col\] file1 file2 ...

Command line options:

- **-f** format

  : input file format to be read (default is ascii, **--formats** for full list)

- **-p** fileprefix

  : change prefix to ALL settings files read/written by splash

- **-e**, **-ev**

  : use default options best suited for line plotting (.ev files)

- **-360**

  : set default options suited to 360 video

- **-b**, **--buffer**

  : buffer all data files into memory

- **-o** pixformat

  : dump pixel map in specified format (use just **-o** for list of formats)

Command line plotting mode:

- **-x** column

  : x axis

- **-y** column

  : y axis

- **-r\[ender\]** column

  : column to render (will use 1 and 2 as x,y if **-x**,-y not specified)

- **-vec\[tor\]** column

  : vector quantity to plot with arrows

**-c\[ontour\]** column : contoured quantity

- **-multi**

  : multiplot

- **-dev** device

  : specify plotting device on command line (e.g. **-dev** */xw*)

- **--movie**

  : shortcut for **-dev** */mp4* to make a movie from plot sequence

- **--xsec**=*1*.0

  : specify location of cross section slice

- **--kappa**=*1*.0

  : specify opacity, and turn on opacity rendering

- **--anglex**=*30*

  : rotate around x axis (similarly **--angley**, **--anglez**)

- **--code**

  : enforce code units (also **--codeunits**)

- **--sink**=*1*

  : centre on sink particle number 1

- **--origin**=*666*

  : set coordinate system origin to particle number 666

- **--origin**=*maxdens*

  : set coordinate system origin to particle at maximum density

- **--track**=*666*

  : track particle number 666

- **--track**=*maxdens*

  : track particle at maximum density

- **--exact**=*file1*,f2

  : read and plot exact solution from ascii files file1 and f2

- **--sort**

  : sort filenames for comparison (e.g. snap\_000 snap1\_000 snap2\_000)

Example data formats (type **--formats** for full list):

- **-ascii**,-csv

  : ascii text/csv format (default)

- **-phantom** **-sphng**

  : Phantom and sphNG codes (auto)

- **-vtk**

  : vtk legacy binary format (auto)

- **-ndspmhd**

  : ndspmhd code (auto)

- **-gandalf**,-seren

  : Gandalf/Seren code

- **-gadget**

  : Gadget code (auto)

This build does not support HDF5. Compile with HDF5=yes to change this. This build does not support FITS. Compile with FITS=yes to change this.

### Convert mode:

- splash to ascii

  : convert to ascii; type "splash to" for other formats

### Grid conversion mode:

- splash to grid

  : interpolate to grid; type "splash to" for details

### Analysis mode:

- splash calc \<mode\>

  : type "splash calc" for details
