1. Description of STARTIMES File

1.1. Description of STARTIMES file generated by OUTMOD

1.1.1. General comments

A time series generated by OUTMOD is identified by a time series number and a version number. Response type is identified by the time series number, see description below. The selected node number or element number is identified by the version number.

For one response type versions are numbered 1,2,3,4…​…​N according to:

  • version 1 for 1st selected element/node,

  • version 2 for 2nd selected element/node,

  • …​

  • version N for last selected element/node

Time series number and version number are printed to OUTMOD result file for each selected response. In addition, FEM element/node number is included in identification text for each time series stored on STARTIMES file.

1.1.2. Example

Output of time series of dynamic axial force for element 1, 33, 45 is specified in OUTMOD. Identifiers to generated time series are:

  • Element 1: 40.01 (time series number 40, version number 1)

  • Element 33: 40.02 (time series number 40, version number 2)

  • Element 45: 40.03 (time series number 40, version number 3)
