abstract = {This paper introduces a generalised inverse modelling
framework, called PROPTI, with application examples in
pyrolysis modelling. It is an open source tool, implemented
in the programming language Python. With its generalised
formulation, it is tailored to enable communication between
arbitrary simulation models, different optimisation
algorithms, as well as various experimental data series as
optimisation targets. The framework aims to facilitate high
performance computing resources, via multi-threading and the
Message Passing Interface(MPI), in order to speed up the
overall process. As simulation models, Fire Dynamics
Simulator (FDS) and OpenFOAM are utilised during the
presented work. A mock-up of a thermogravimetric analysis
(TGA) is used for verification and shows that PROPTI can be
employed to determine material parameter sets from
experimental data. In this example, based on an artificial
data set, the simulation data converges towards the exact
solution. A series of mass loss calorimeter (MLC) tests
provide real world examples. Here, the mass loss rates (MLR)
of poly(methyl methacrylate) (PMMA) samples, subjected to
different irradiance levels, were used. They provide target
data sets for two different optimisation algorithms:
shuffled complex evolution (SCE-UA) and fitness scaled
chaotic artificial bee colony (FSCABC). The resulting, i.e.
best fitting, material parameters are used for pyrolysis
simulation with FDS. The convergence of the results and the
performance of different optimisation strategies are
discussed, by comparing the resulting simulation data and
convergence series. In order to demonstrate the capability
to use simulation tools other than FDS, a mock-up example in
OpenFOAM for the steady state simulation of an iron beam,
placed under lateral stress, is presented. The PROPTI
framework is not limited to time series as target data, but
any kind of data sets can be used. Combinations of temporal
and spatial data can be used and may open new optimisation
targets and approaches for the determination of pyrolysis
parameters.},
