Abstract:
Computer modelling has become an important aspect of engineering
science and technology. Bespoke computer models are routinely under
development and are often applied to specific manufacturing and materials
processes. Solidification
processing
(casting for example) is no exception and
significant numbers of modelling approaches
for solidification
are
available
in
literature.
The roles of verification and validation in
model development
for any
physical process ought to be clear, but owing to practicalities, it can be difficult to
fully
verify or
fully
validate a computer model to a specific requirement. Hence,
the terms verification and validation are routinely interchanged or are
misconstrued to mean the same thing.
This paper outlines a verification study for
a Bridgman Furnace Front Tracking Model (BFFTM) of solidification. A formal
order verification procedure was applied which showed that the prediction from
the computer model converged, in agreement, with an analytical model of the
same process.
Hence,
verification
of the BFFTM was achieved
