ASCII Output File (STA-File)

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

The purpose of this STA-file is to save the state of element and then make it possible to include it into a _0000.rad file for RADIOSS Starter.

The state file name is Runname_nnn#.sta, where Runname is the Run Name (see /RUN) and nnn# is the file number (four digits) from 0001 to 9999.

Setup in RADIOSS Starter and Engine

The Runname_nnnn.sta is written by entering the following keyword in the RADIOSS Engine files. This must be set in /STATE/DT in the Engine file.

/STATE/DT

Tstart Tfreq

Part_ID1 ... Part_IDN

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

As of Version 11.0, /STATE/STR_FILE can also be used in Engine file to write /INISHE, /INISH3 and /INIBRI in a separate file, which can be compressed (using GZIP).

This file can be read in Starter with the same keyword /STATE/STR_FILE (see Use Runname_run#.sta file).

Comments

1.	The 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.

2.	First line is always “#RADIOSS Runname_nnnn.sta” according to the /IOFLAG keyword.

3.	The Runname_nnnn.sta file always finishes with “#ENDDATA”.

#ENDDATA

Use Runname_run#.sta file

The state files can be used to impose initial state on shell or solids in subsequent runs through the keyword #include or through the keyword /STATE/STR_FILE to read the stress file.

#include TEST_LOI70_0011.sta

/STATE/STR_FILE

TEST_LOI70_0011.sta

Comments

1.	The STA-file contains node and element. Delete the concerned nodes from the node definition of the 0.rad and concerned elements from the element definition (for example: /BRICK /SHELL ...) of the 0.rad; otherwise there will be an error in Starter.
