Comments

  1. Maximum Runname length is 80 characters and the characters "/" and "\" may not be used.
  2. run#: Radioss run number (four digits) from 0000 to 9999.
  3. cpu #: number of SPMD processors (four digits) from 0001 to 9999.
  4. C: restart letter (refer to /RFILE/n in the Radioss Engine Input manual).
  5. In case of Single File Input, Engine options can be added into Starter file. Refer to Single File Input for details.
  6. Though the current version of Radioss is able to read 4.x extension input files, output files always follow 12.x extension format.
