ASCII Output File (STY-File)

ASCII Output files are formatted output files from RADIOSS Starter and RADIOSS Engine.

The purpose of these files is:

•	Provide users with an ASCII output format displaying information similar to that displayed by animation files.

•	Input format for initial stress or strain files.

By default these files are written under the name Runname_run#.sty (Irootyy ≠ 2), or RunnameYnnn (if Irootyy = 2) according to /IOFLAG (Irootyy flag) in RADIOSS Starter.

With, nnn being the output file number and run# is the RADIOSS run number (four digits) from 0000 to 9999.

This provides a description of the output files and initial conditions in case of OutyyFMT ≠ 2 (/IOFLAG), which is the default, writing 10 digits integer and 20 digits real.

Previous format can be retrieved by using OutyyFMT = 2, writing the same information with 8 digits integer and 16 digits real.

Runname_0000.sty Files

The Runname_0000.sty file is created by RADIOSS Starter using Ioutp = 1 in the /IOFLAG keyword.

#---1----|----2----|----3----|----4----|----5----|----6----|----7----|----8----|----9----|---10----|

# IPRI IGTYP IOUTP IOUTYY IROOTYY

0 0 1 0 0

#---1----|----2----|----3----|----4----|----5----|----6----|----7----|----8----|----9----|---10----|

This file contains general information on the model and is compulsory in order to be able to use subsequent output files.

Runname_0000.sty file information is structured in sets, using the following syntax:

/“Keyword” -> type of information

Full name of information

#FORMAT: -> data format (in Fortran) for this set.

Format is always I10 for (Integers) and G20 for (Real).

# -> name of each data

1.	The first column of data represents the system number. The second column is your number. Element definition always refers to system numbers.

2.	The three first lines of an element are always written, even if there is no element of that type. In such a case, a line is left blank below the option.

3.	First line is always: “#RADIOSS Output File V21 RunnameY000” or “#RADIOSS Output File V21 Runname_nnnn.sty” according to the /IOFLAG keyword.

4.	The second line contains “/HEAD”, and the third is the title of the model (format is A100).

Runname_run#.sty Files

The Runname_run#.sty is written by entering the following keyword in RADIOSS Engine files:

/OUTP/DT

Tstart Tfreq

OUTP files are written with a time frequency Tfreq, the first file being written at time Tstart.

Data is written in the same format as in the Runname_0000.sty file.

Runname_run#.sty files contain the following default information:

#RADIOSS Output File V21 Runname_run#.sty (or RunnameYnnn)

With Runname being the root name of the computation and nnn the number of the file written (or run# is the RADIOSS run number (four digits) from 0000 to 9999).

•

/GLOBAL

Contains: Time, internal energy, kinetic energy, rotational kinetic energy, and external force work for the complete model.

•	/MATER /material number (internal number, 10 digits)

First line contains: User number, internal energy, and kinetic energy.

Second line contains: X momentum, Y momentum, and Z momentum.

•	/NODAL/VECTOR/COORDINATE

Nodal coordinates.

Other information may be output using the following keywords in the Engine file:

•	/OUTP/Keyword2 for scalar information

•	/OUTP/ELEM/Keyword3 for element scalar information

•	/OUTP/VECT/Keyword3 for vector information

•	/OUTP/BRIC/Keyword3/Keyword4 for brick tensor information

•	/OUTP/SHEL/Keyword3/Keyword4 for shell tensor information

Keywords are the same as for animation files, except:

EPSDOT is not available as a scalar, but is available for shells as a tensor.

/OUTP/BRIC/STRESS gives the stress tensor for bricks, keywords SIGX, SIGY ... are not available.

Variables are given by the following lines:

•	/OUTP/Keyword2/Keyword3/Keyword4

Each keyword is formatted on 10 characters.

Keyword2 is the type of node / element: NODAL, SHELL, SOLID

Keyword3 is the type of variable: SCALAR, VECTOR, TENSOR

Keyword4 is the name of the variable

Variables are written in the order of their system number. For shell elements, 4-node elements are written first, followed by 3-node elements.

Output files always finish with the keyword ‘/ENDDATA’.

/ENDDATA

Initial Conditions Definition using Output Files

The output files can be used to impose initial conditions on shell or solids in subsequent runs through the keyword /INISTA.

Both Runname_run#.sty and Runname_0000.sty files are required.

The following variables can be initialized:

For nodes:

•	Initial coordinates

•	Initial velocities

For solids:

•	Plastic strains

•	Internal energy

•

Density

•	Stresses (if energy and density are provided, pressure is overwritten)

For solid elements, initial conditions are compatible with Material Laws 1, 2, 3, 4, 6, 36 and user laws, if the formulation is incremental.

For shells:

•

Stress

•

Strain

•	Plastic strain

•

Energy

•

Thickness

•

Hourglass

•

Forces

For shell elements, initial conditions are compatible with Material Laws 1, 2, 36 and user laws.

The Runname_run#.sty file is defined with the /INISTA keyword in the RADIOSS Starter.

The Runname_0000.sty file is required to associate the data given in Runname_run#.sty files with node and element identification.

The model used to write the Runname_0000.sty or Runname_run#.sty files can be identical or different from the current model (though it must always have a different root name).

If the models are different, the Runname_0000.sty must contain less elements than the Runname_0000.rad file.

Strain tensor for shells is only needed for Material Law 36 with tension failure option or users law.
