Output and Restart

When FrontISTR is executed, it outputs a log file, a results file, and visualization data. Whether each file is output and what it contains depend on the analysis content and the specifications in the analysis control data.

Results File

The results file is enabled with !WRITE,RESULT, and the output variables are selected with !OUTPUT_RES. It stores the physical quantities per node and element for post-processing and for reading into another analysis. For the file names, placement, and how to check them after a run, see the execution guide.

The results file (extension .res) is text data with the following structure: a format version and comment at the top, then the global variables, and finally the output variables per node and element.

*fstrresult 2.0
*comment
<comment>
*global
<the number of global parameters>
<dof of global parameter> ...
<label of global parameter>
...
<value of global parameter>
...
*data
<the number of nodes> <the number of elements>
<the number of node variables> <the number of element variables>
<dof of node variable> ...
<label of node variable>
...
<value of node variable>
...
<dof of element variable> ...
<label of element variable>
...
<value of element variable>
...

Log File

The log file (extension .log) is a summary file that is always output after an analysis. In addition to the physical quantities per node and element, it outputs the maximum/minimum values of the displacement, strain, and stress components. For eigenvalue analysis, the eigenvalues and eigenvector values are output. For the file name and placement, see the execution guide.
