Computer-based evaluation dilemma.
9.4.3 Finite Element Analysis
FEA is now a fully accepted analysis system. The predictions it makes for stresses, strains,
etc. are wholly acceptable as predictions of “real life.”
9.4.4 Computational Fluid Dynamics
As with FEA, CFD is an accepted system for evaluating the performance of a device -
provided you follow the GIGO principle.
9.4.5 Caveat
Any computer-based evaluation package you use will come with a caveat stating “the use
of this software does not replace physical evaluation.” While this is true, there are certain
circumstances where physical evaluation and simulation coincide. You will need guidance by
qualified, chartered/licensed engineers to make this judgment.
9.5 Value to “Healthcare” Analysis
At some point you will need to prove your device to the purchasing body, irrespective of the
support given by clinical staff. This will always revolve around the “value” of the device.
l
Will it be cheaper?
l
Will it save money in the short term?
l
Does it have economic benefits in the long term?
