Define parts to be output to the state file using part_IDn
All nodes in the model will be output to the state file.
Tstart Start time  
Tfreq Time frequency  
part_ID1 ...


If Keyword3 is blank, required list of parts whose state output is written to the state file.  


  1. Writes state files (.sta) at a time frequency equal to Tfreq, the first file being written at time Tstart. 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.

    A state file gets a format which makes it possible to include it into a _0000.rad file for Radioss Starter.

  2. The nodes IDs and actual coordinates of the corresponding nodes are written in each state file into a /NODE block.

    The element IDs and connectivities of the elements are written in each state file using the elements definition block such as, /SHELL, /BRICK, /BEAM, etc.

    The state output fields (stresses, strains, ...) asked for output into the state files are written only for the elements belonging to those parts ID requested or if Keyword3=ALL, then all parts.

  3. It is recommended to use /STATE/SHELL/STRESS/FULL, /STATE/SHELL/AUX/FULL and /STATE/SHELL/STRAIN/FULL for being able to completely restore the state of shells elements and /STATE/BRICK/AUX/FULL, /STATE/BRICK/STRAIN/FULL, /STATE/BRICK/STRES/FULL to restore the state of solid elements.
  4. In case of adaptive meshing, a /STATE/ADMESH block is written, which includes the description of the mesh data structure. This block is needed for running another stage.
  5. Blocks /INISHE, /INISH3, /INIBRI, /INIBEAM, etc. can be written in a separate file using /STATE/STR_FILE.
