Description of used file extensions in GENSYS   

Introduction

GENSYS works with a number of files. In order to distinguish between the files, each type of file has its own extension. This manual presents a brief summary of the contents and origin of the files.

For having a better overview of all files the user can chose to store the files in subdirectories. In order to have the files sorted in subdirectories, the user must define the environment variable $gendir and give $gendir the value= yes. The name of the subdirectories are defined in the file $gensys/scripts/gen_defs.

Files in CALC

Files in program group MISC.

Files in GPLOT.

Input data files:

Program GPLOT does not produce any files which can be read by other programs in GENSYS. The only output is graphical output.

Files in KPF.

Files in MPLOT.

In addition to the above, also graphical output formats.

Files in NPICK.

Files in TRACK.

In addition to the above, also graphical output formats.

Files in OPTI.

All file extensions in alphabetical order.

calc.out

The memory dump of program CALC. The file contains the total memory of program CALC, generated in the most recent calculation. The file can be used for the users information or for debugging purposes.

*.cata

Output from the program MPLOT, containing a list of all variables and scalars in current ident. The *.cata-file is only written if command catalo has been given in the input data file to program MPLOT.

*.cmplx

General data file written in complex precision, the file comprises four columns: X-real, X-imaginary, Y-real, and Y-imaginary.

*.four

Fourier spectra written in complex precision, the file comprises four columns: complex angular frequency two columns and complex amplitude two columns.

*.frespf

Main input data file for the program FRESP.

*.ftransf

Input data file for the program FTRANS

*.funcf

Input data file for the program FUNC

*.gencryptf

Input data file for the program GENCRYPT

*.gp

Output data in GPdat-format from a calculation in QUASI, MODAL, or TSIM. The output data contains deformation shapes of the structure. The deformations can be animated in program GPLOT, or they can be used as initial values in program CALC using command INITVAL. The file is written as a formatted file, but it is rather complex. In order to make it more readable for humans the user can filter the file through program cata_gp.

*.id

Result file written in MPdat-format containing scalars and curves from a calculation in one of the programs QUASI, MODAL, FRESP or TSIM. The file is unformatted and cannot directly be read by an ordinary editor, in order to inspect the contents of the file the user has access the programs catas and cataf which translates the file into a formatted ASCII-file.

*.kc_propf

Input data file for the program KC_PROP

*.kc_propr

Result data file from the program KC_PROP

*.kpf_plotf

Input data file for the program KPF_PLOT

*.kpf_rotf

Input data file for the program KPF_ROT

*.kpf_turnf

Input data file for the program KPF_TURN

*.kpff

Input data file for the program KPF

*.kpfr

Output data file from the program KPF.
The file contains the following wheel-rail geometry functions:

cpt_$1.drfn	Rolling radius v.s. lateral position
cpt_$1.gamfn	Contact angle v.s. lateral position
cpt_$1.zfn	Vertical wheel lift v.s. lateral position
cpt_$1.rofn	Difference in lateral curvature v.s. lateral position
cpt_$1.poswfn	Position of contact point on wheel v.s. lateral position
cpt_$1.posrfn	Position of contact point on rail v.s. lateral position

Sometimes the kpfr-file contains a special description of the flange. The flange geometry functions has the same names as above, but cpt_ is replaced with cpf_.

*.list

Listing file of an output data file in MPdat-format or GPdat-format. The list files are generated with the script cataf or catas for the MPdat-file, and cata_gp for the GPdat-file.

*.mauz

Track irregularity file measured in a track measuring car type: Mauzin, Plasser & Theurer, Matisa, or similar track recording vehicle with rollers following the rails making versine measurements. The file is built-up as follows:

Line 1)

Text string indicating that this is a track recording file. The text string also gives information about which program that has created the file.

Line 2-4)

Ident text which was given to the program which created the file.

Line 5)

Blank line.

Line 6)

Information on how the track recording file has been created, the following commands are understood:

END	=	Leading end, A or B.
DXTRAC	=	The equidistance between the track data points in longitudinal direction.
NPCURV	=	Number of track measurement points in the actual file.
XSTART	=	Start coordinate of the track.
LTOT	=	Length of the track.

Line 7)

Scaling factors which have been used. The scaling factors are written in the same order as the columns are printed.

Line 8)

Information stating what is meant by the columns in the print below.

Line 9-)

Track recording data written in columns. The columns include the following information:

	Column	1)	Longitudinal distance in [m].
	Column	2)	Level irregularity, right side [mm].
	Column	3)	Level irregularity, left side [mm].
	Column	4)	Mauzin cant irregularity [mm] (Not Used)
	Column	5)	Twist irregularity [mm]
	Column	6)	Horizontal versine, right side [mm].
	Column	7)	Horizontal versine, left side [mm].
	Column	8)	Gauge [mm].

The columns in the track recording files are often written in format (8F8.2), but any format can be used because all track programs reads the file in free format. Left and right side refers to the side of the coach when an observer stands in the carriage facing end A, with his/her back to end B. The observer's right side is on the right side of the coach.

An example of a track recording file:

Positive direction for the Y-coordinate is toward the center of the track for both rails. Positive direction for the Z-coordinate is downwards. The measurements should be accurate, preferable more than one point per 0.1 [mm] in lateral coordinates. Example of an input data file describing a rail profile:

  30.16      8.40925   to the gauge measuring point, i.e. 32.5 mm from origin.  
  30.24      9.24991   The normal case is that the rail profile is curved in    
  30.32     10.27144   a way yielding the profile line to be vertical at the    
  30.40     11.61505   gauge measuring point. This means that no more data of   
  30.48     13.98782   the rail can be treated.                                 
                                                                                

The origin of the rail profile is defined to be a distance RAIL_FL_ORIGO from the gauge measuring point. The gauge measuring point of the rail is defined as follows: the gauge measuring points are the two points on right and left rail located in a vertical interval between top of rail and 14 mm below top of rail which are closest to each other.
For ideal normal gauge tracks, the following is valid:
Lateral semi-spacing between the gauge measuring points = 717.5 mm
Lateral distance between the gauge measuring point and origin RAIL_FL_ORIGO= 32.5 mm
Lateral semi-spacing between "The Nominal Running Circles" = 750 mm

*.stat2

Stat2fil created by MPLOT with the command stat2

*.trac

Trac-file containing track irregularities. The coordinate systems defined in the model follows the designed track geometry, and deviations in the track alignment relative to the designed track geometry is called track irregularities. The trac-file is an ASCII-file containing the following information:

Column 1)	Distance along the track (m).
Column 2)	Lateral deviation of track center line (mm). Positive displacement to the right
Column 3)	Vertical deviation of track center line (mm). Positive displacement downwards
Column 4)	Gauge irregularity (mm) Measured at the gauge measuring height, 14[mm] under rail top level.
Column 5)	Cant irregularity (mm) Height difference between right and left rail Positive if the right rail is lower than left rail

Columns in trac-files are written in format (F6.1, 4F10.2).

*.trax_wdesign

In addition to the trax-file the trax_wdesign-file also contains the designed track geometry. The trax_wdesign-file is an ASCII-file containing the following information:

Column 1)	Distance along the track (m).
Column 2)	Lateral deviation of track center line (mm). Positive displacement to the right
Column 3)	Vertical deviation of track center line (mm). Positive displacement downwards
Column 4)	Gauge irregularity (mm) Measured at the gauge measuring height, 14[mm] under rail top level.
Column 5)	Cant irregularity (mm) Height difference between right and left rail Positive if the right rail is lower than left rail
Column 6)	Designed track curvature [1/m]. Positive in a right handed curve
Column 7)	Designed cant [rad]. Normally positive in a right handed curve
Column 8)	Vertical position [m]. Positive displacement downwards

*.wheel

Data file describing a wheel profile.
The wheel profile is described in Y- and Z- coordinates. The coordinates should be measured in millimeters. Positive direction for the Y-coordinate is toward the center of the track for both wheels. Positive direction for the Z-coordinate is downwards. The measurements should be accurate, preferable more than one point per 0.1 [mm] in lateral coordinates. The origin of the Y-coordinates should be at the radius where the wheel diameter of the wheel is measured, this diameter is sometimes also called "The Nominal Running Circle".

For normal gauge tracks, the following is valid:
Lateral semi-spacing between the wheels = 680 mm
Lateral distance between inside of the wheel and "The Nominal Running Circle" = 70 mm
Lateral semi-spacing between "The Nominal Running Circles" = 750 mm
