# Script
# freefoam-solverSweeps
#
# Description
# Extracts statistics from a log file
#
#------------------------------------------------------------------------------
"""Usage: freefoam solverSweeps [-h, -help] [<log>]
This utility script extracts solver statistics from a log file and prints them
to the screen. The extracted quantities are:
- execution time of the first iteration
- overall execution time
- the number of iterations
- the first iteration number
- the last iteration number
- the number of solver sweeps for the velocity and pressure fields
Options
-------
-h, -help Print this help message
<log> Analyze this log file. If this is -, read log from standard input.
If not specified, the name of the file (NOT the data) is read from
standard input.
