3.3. Replay a Problem¶
Once a simulation is completed, one might want to compute other fields of the solution. This can be
done with cbcposts Replay
-functionality. The process can be done in very few lines of code.
In the following, we initialize a replay of the heat equation solved in A Basic Use Case and restarted in Restart a Problem. First, we set up a postprocessor with the fields we wish to compute:
from cbcpost import *
from dolfin import set_log_level, WARNING, interactive
set_log_level(WARNING)
pp = PostProcessor(dict(casedir="../Basic/Results"))
pp.add_fields([
SolutionField("Temperature", dict(plot=True)),
Norm("Temperature", dict(save=True, plot=True)),
TimeIntegral("Norm_Temperature", dict(save=True, start_time=0.0, end_time=6.0)),
])
To replay the simulation, we do:
replayer = Replay(pp)
replayer.replay()
interactive()
