yancpars - add YANC parameters to an existing snapshot [deprecated]
yancpars [parameter=value]
This program is deprecated,
though the source code is still available, because of its unique character.
yancpars adds YANC integration parameters to a snapshot. It will only read
the first snapshot, and discard all others. Use csf(1NEMO)
or snaptrim(1NEMO)
to select an arbitrary snapshot. In addition, any double precision snapshots
will be converted to single precision, since that is what YANC wants.
The
following parameters are recognized in any order if the keyword is also
given:
- in=
- Input file, must be a snapshot file. No default.
- out=
- Output
file, in snapshot format. No default.
- eps=
- Softening length [0.05]
- kernel=
- Softening kernel. See below for an enumeration of this integer parameter
[21]
- theta=
- Treecode opening angle [0.5]
- hmin=
- Timestep dt=2^-hmin
[5.0] -- is this an integer or real -- 26-may-01 PJT [1.0]
- convert=
- Convert
certain types in the input data to another type. Normally YANC wants single
precision, so any double will be converted to single. [d2f].
The
following softening kernels are available:
1-9 Ferrers softening, ’kernel’ is the index
10-19 ...
20 P0, the classic Plummer softening
21 P1
22 P2
23 P3
30 experimental
