# freefoam-graphExecTime(1)

Computes the time used per iteration

## NAME

freefoam-graphExecTime - Computes the time used per iteration

## SYNOPSIS

**freefoa graphExecTime** *\<logFile\>*

## DESCRIPTION

This utility computes the time used per iteration in seconds and writes it to the file *executionTime.dat*. The file has the following format:

```
Solver Performance
iterations
time/iteration
0 0
0 0
1
time
0
<nIterations>
1.000000 <time/iter1>
2.000000 <time/iter2>
3.000000 <time/iter3>
4.000000 <time/iter4>
5.000000 <time/iter5>
...
```

where *\<nIterations\>* is the number of iterations and corresponds to the number of lines which are following this entry. *\<time/iterX\>* is the time this iteration requried.

## OPTIONS

*\<logFile\>*

A FreeFOAM log file (i.e. the screen-output created by a FreeFOAM solver)
