  The design of microfluidic devices is a cumbersome and tedious process that
can be significantly improved by simulation. Methods based on Computational
Fluid Dynamics (CFD) are considered state-of-the-art, but require extensive
compute time - oftentimes limiting the size of microfluidic devices that can be
simulated. Simulation methods that abstract the underlying physics on a higher
level generally provide results instantly, but the fidelity of these methods is
usually worse. In this work, a simulation method that accelerates CFD
simulations by exploiting simulation methods on higher levels of abstraction is
proposed. Case studies confirm that the proposed method accelerates CFD
simulations by multiple factors (often several orders of magnitude) while
maintaining the fidelity of CFD simulations.
