Accuracy vs. computational time: Translating aortic simulations to the clinic

Sophisticated Fluid-Solid Interaction models are currently computationally intractable for routine clinical application, but capture the important physical phenomenon of finite wave speeds in arteries. Recognising that, at least to a first linear approximation, the one dimensional wave equation for a compressible fluid is exactly that for a distensible tube, this paper proposes a novel approach to arterial computational fluid mechanics using this analogy. The execution time is typically four times lower than an FSI analysis, and only 10% higher than for a simple incompressible fluid analysis. This has major implications for clinical translation.
