Name

yancpars - add YANC parameters to an existing snapshot [deprecated]

Synopsis

yancpars [parameter=value]

Description

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.

Parameters

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].

Softening Kernel

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
