Command line arguments

The following is a list of command-line arguments for navsetup:

-h	Prints the list of parameters and a short description and prints the version number of NaSt3DGP.
-s $\langle$SceneFile$\rangle$	Reads the scene description file $\langle$SceneFile$\rangle$ and generates a data-file
-b $\langle$DataFile$\rangle$	The name of the data-file, the default name is default.bin
-l $\langle$DataFile$\rangle$	load field variables(velocity, pressure etc.) from an existing datafile. This is useful if you want to run a calculation with previsously computed values $p,~{\bf u}~\{,~T,~c,~..\}$ but want to change some simulation parameters. You can create a binary file for the new calculation with the following command: navsetup -s $\langle$SceneFileNew$\rangle$ -b $\langle$DataFileNew$\rangle$ -l $\langle$DataFile$\rangle$ The data will be interpolated if the number of grid points changes.
-L $\langle$DataFiles$\rangle$	Same as -l, but reads several data files $\langle$DataFiles$\rangle$.*.
-A $\langle$TextFiles$\rangle$	Same as -L, but reads several text files (written by ${\tt -a}$) $\langle$TextFiles$\rangle$.txt.*.
-o $\langle$OutFile$\rangle$	This option sets the base of the filename to $\langle$OutFile$\rangle$ for the options which write files. If this option is not used, $\langle$OutFile$\rangle$ is set to 'default'.
-TC $\langle$DataFile$\rangle$	Reads the data $p,~{\bf u}~\{,~T,~c,~..\}$ from the data-file and writes to $\langle$Outfile$\rangle$.dat. The file format is ASCII Tecplot. The data written is located at the cell centers.
-T $\langle$DataFile$\rangle$	same as $-TC$ but writes each field to a separate file named $\langle$Outfile$\rangle$.$\langle$field$\rangle$.dat, e.g. $\langle$Outfile$\rangle$.u.dat .
-g $\langle$DataFile$\rangle$	Reads the data $p,~{\bf u}~\{,~T,~c,~..\}$ from the data-file and writes each of it in $\langle$Outfile$\rangle$.u, $\langle$Outfile$\rangle$.v etc. These files can be read in Matlab with the script tools/matlab/ReadNast.m.
-a $\langle$DataFile$\rangle$	Same as $-g$, but use ASCII-format(text files) which are named $\langle$OutFile$\rangle$.txt.*.
-G $\langle$DataFile$\rangle$	Reads the data $p,~{\bf u}~\{,~T,~c,~..\}$ from the data-file and writes each of it in $\langle$Outfile$\rangle$.vtk.u, $\langle$Outfile$\rangle$.vtk.v etc. The files are written in the VTK5.1 rectilinear grid format.
-GS$\langle$DataFile$\rangle$	same as $-G$ but uses the VTK Structured Points format and the files are named $\langle$Outfile$\rangle$.vtksp.* .
-f $uvwptcV$	create a VTK file including the velocity-field $V$ or multiple scalars $u, v, w, p ,t, c0\dots cN~.$ This option has to be used together with $-G$, e.g. use the command navsetup -f $Vp$ -G $\langle$DataFile$\rangle$ -o $\langle$Outfile$\rangle$ to write the the velocity as a vectorfield and the pressure $p$ to a file named $\langle$Outfile$\rangle$.vtk.mix or use navsetup -f $puv$ -G $\langle$DataFile$\rangle$ -o $\langle$Outfile$\rangle$ to write the pressure $p$ and the first two velocity components $u$ and $v$.
