Radioss Files

Input Format

The input format (V41, V44, V51, V90, and so on) corresponds to the format of the Radioss input data file, whose name is RunnameD00 for input formats up to V44 or Runname_0000.rad for input formats coming from V51 or higher.

For input formats up to V44, the input format is declared at the first line of the Starter input file. This conforms to the version of the input manual.

For input formats from V51 onwards, the input format is declared in the keyword /BEGIN, which must be the first uncommented line after the line: “#RADIOSS Starter”.

For every new Radioss main release (V41, V44, V51, V90, and so on), a new input manual is provided, which presents the characteristics of the new input format, and information on new keywords.

By ascending compatibility, a RunnamD00 or Runname_0000.rad file conforming to a given manual will be read normally by the next Radioss release (but not the opposite).

For instance, a file with format V41 will be read normally by V44 of Radioss, while a file with format V42 cannot be used with V41. In this last case, an error message is given by Radioss Starter:
** ERROR IN INPUT FORMAT
INPUT VERSION 42 IS NOT SUPPORTED

Version 12.0 and After

Radioss versions 12.0 and after are all based on 12x extension format.
