Hi,

I would like to plot the residuals and the force coefficients of my simulations on-the-fly. Therefore, I have created two files for gnuplot as explained in Wolfgang Heydlauff's tutorial:
Tutorial of how to plot residuals !

However, I am running my case not from the command line but with an Allrun script like the following:

Code:
#!/bin/sh
cd ${0%/*} || exit 1

# Source tutorial run functions
. $WM_PROJECT_DIR/bin/tools/RunFunctions

# copy 0.orig to 0
cp -r 0.orig 0

# Create mesh
runApplication blockMesh

# Initialise with potentialFoam solution
runApplication potentialFoam

rm -f 0/phi

# Run the solver
runApplication $(getApplication)

#------------------------------------------------------------------------------
After the simulation is terminated I am able to call the scripts with

gnuplot Residuals -
gnuplot forceCoeffs -

to see the iteration results but I would like to see the graphs during the simulation already.

How can I modify my Allrun script to enable the on-the-fly plotting of residuals and force coefficients?
