JP,
Thank you.
One more polite request: my ASCEND models have by now become so big that I
am no longer able to navigate the PyGTK "Integrator" tab comfortably. Ctr-C
does not seem to work i.e. I am unable to copy data from the PyGTK
"Integrator" tab for further analysis in R. Could you direct me to the best
starting point to learn how to control ASCEND integration? At this stage I
am "only" trying to be able alter the values of input signals over time and
save the values of observed variables to an ASCII file. I did notice files
like ${HOME}/ascend/models/dyn_tank.a4s, for example, but how do I get them
(or something similar) executed?
Regards,
DFE
