OpenCFD would like to acknowledge and thank Marco Kiewat for his contributions, elaborate suggestions and help, and critical recommendations. Highly appreciated.
Problem
OpenFOAM currently lacks one of the key advantages of DMD:
the capability to generate a field based on given modes and their associated dynamics, without the need for any CFD computations at arbitrary intermediate and/or future time points.
This functionality would allow users to condense an entire simulation into a few modes and mode dynamics, and subsequently generate fields at any desired time or predict their future states of periodic or pseudo-periodic systems, all without the need for additional CFD analyses.
Solution
Implement and verify the method proposed by Kiewat (2019) to generate time-variant field data from DMD data for a set of specified times.
