Hi Anton, read https://www.yade-dem.org/sphinx/user.html#checkpoints -- although it talks about loadTmp, the same applies to O.pause() etc. Calling O.pause() from inside the engine will (though it might depend on exact timing between python and computation threads, and that is probably the reason why you sometimes get the simulation paused and sometimes not) have no effect, modifying engines from inside the loop might lead (I would guess) to crash and calling O.run() will have no effect either.
Currently we have no proper method for modifying engines on the fly, from inside, although I thought a few times about something like O.postIterHook that could be used to postpone python code execution after the current iteration (if non-empty); that code could modify O.engines safely. Now, you can solve your problem with something like: def feedIsFinished(): if condition: O.stopAtIter=O.iter+1 # stop exactly after this simulation O.run() O.wait() # will block until the simulation is stopped from inside feedIsFinished # modify engines here as you want O.run() # continue with modified engines sequence OR, you can set zero translation for the translation engine; deleting the bodies is safe without pausing the simulation. HTH, v. > I pause simulation for a while, delete some engines, delete some bodies and > then start the simulation again. > In this step simulation sometimes terminates, not always, but it happens. > > What do I do wrong? _______________________________________________ Mailing list: https://launchpad.net/~yade-users Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
