Good Day folks.
Was wondering if anyone could tell me if OMNET++ supports replaying
parts of the simulation from the Log files.
For example: if you've ran a simulation and received a Log file, could
you possibly use the Log file to show the simulation (or parts of it)
running graphically?
If this function is possible, could you please tell me how it's done
(or point me to a similar example)?
Thanx a million,
M. Friedmann

Hi,
As far as I know this is NOT possible, if your simulation shows some
errors at a given simulation time you have to run it again in the
graphical environment and for example use the "run until" to simulate
fast until close to your error and then continue interactively on a step
basis
Hope this helps

Thank you very much, Patrick.
Does anybody else know if this is possible?

Well, we have been thinking about that feature, but of course, you cannot store the whole state of your simulation at each event, so the playback would be limited to the graphical representation only (i.e. inspecting variables, statistics would not be possible). The playback feature will be implemented only, when we move to java based runtime environment (implementing it in the current TKenv is not feasible)...
If you want to create a demonstration without delivering the real simulation, at the moment I recommend some kind of screen capturing...
On the bright side: omnet is already prepared to dump all log information that would be required to create such a player. The log format is documented, so it is possible to implement a player in any language you wish if you need it badly...
We are already using this log (called event log) in our sequence chart view which is a kind of playback tool already. (it just does not deal with appearance changes (ie ignores the display string changes) and uses the horizontal dimension as time dimension, so you can follow the message passing in a diagram... If you want to debug your simulation/protocol I highly recommend to check it... It is more suitable to find issues in a protocol than a simple playback program...
