Recording data is possible when running real-time and non-real-time (as fast as the computer will run). In order to record data, it is necessary to create a "data recording file". You may create the file using a GUI called dre (data recording editor --- aka Dr. Dre) or you may create it manually.
% cd $HOME/trick_sims/SIM_cannon_analytic
% mkdir Modified_data
% trick-dre &
Figure 3 - Data Recording Editor (dre)
Storing the data recording file cannon.dr
into a directory called Modified_data
is not mandatory. It is just common convention. You may view cannon.dr
it is a
text file.
The simulation must know about the data recording file created in the last section. This is accomplished by adding exec to the simulation input file.
% cd $HOME/trick_sims/SIM_cannon_analytic/RUN_test
% vi input.py
Add the line:
exec(open("Modified_data/cannon.dr").read())
to the top of the input.py
file and then save it.
% cd ..
% ./S_main*.exe RUN_test/input.py
After the simulation runs, data will be dumped into the RUN_test
directory.
The data, in this case, is recorded in binary form.
