Low-Dimensional Modelling of Flow Past a 2D Cylinder with SINDy
A DNS of the 2D cylinder was simulated using 2D_compressible.f90
gfortran 2D_compressible.f90
./a.out
Then, run matlab script main.m for postprocessing vorticity files.
matlab main
main.m finds the POD modes and weights using SVD
The POD weights are then fed into the SINDy alogrithm which finds a best fit of a non-linear DE
The non-linear DE is solved using ODE45 and the results are post-processed with full flow
