Doubly-Adaptive Artificial Compression Methods for Incompressible Flow
share
This report presents adaptive artificial compression methods in which the time-step and artificial compression parameter ε are independently adapted. The resulting algorithms are supported by analysis and numerical tests. The first and second-order methods are embedded. As a result, the computational, cognitive and space complexities of the adaptive ,k algorithms are negligibly greater than that of the simplest, first-order, constant ε , constant k artificial compression method.
