Well done. You've clicked the tower. This would actually achieve something if you had logged in first. Use the key for that. The name takes you home. This is where all the applicables sit. And you can't apply any changes to my site unless you are logged in.

Our policy is best summarized as "we don't care about _you_, we care about _them_", no emails, so no forgetting your password. You have no rights. It's like you don't even exist. If you publish material, I reserve the right to remove it, or use it myself.

Don't impersonate. Don't name someone involuntarily. You can lose everything if you cross the line, and no, I won't cancel your automatic payments first, so you'll have to do it the hard way. See how serious this sounds? That's how serious you're meant to take these.

Accelerating Flow Simulations using Online Dynamic Mode Decomposition. (arXiv:2311.18715v1 [physics.flu-dyn])

Click here to flash read.

We develop an on-the-fly reduced-order model (ROM) integrated with a flow
simulation, gradually replacing a corresponding full-order model (FOM) of a
physics solver. Unlike offline methods requiring a separate FOM-only simulation
prior to model reduction, our approach constructs a ROM dynamically during the
simulation, replacing the FOM when deemed credible. Dynamic mode decomposition
(DMD) is employed for online ROM construction, with a single snapshot vector
used for rank-1 updates in each iteration. Demonstrated on a flow over a
cylinder with Re = 100, our hybrid FOM/ROM simulation is verified in terms of
the Strouhal number, resulting in a 4.4 times speedup compared to the FOM
solver.
