Hi there,

I am going to start learning dynamic mode decomposition (DMD) and wrtie a code for it to further analyze my simulation dada and do better post-processing.

Does any one have a suggestion for me how to start or any comment?

Thank you very much.

Have you got a working code?

Are you also investigating 3D data or only 2D data with your tool?
How do you visualize the modes of the 3D field?

Hi all,
I can recommend http://www.dmdbook.com/

The site provides matlab code without having to buy the book. If you are very determined, the book is a good idea as well. It has helped me a lot to start with DMD, which I used on turbomachine flow fields. What are you guys using DMD for?

Yes this DMD book is a good introduction.
There is also a Python Code available.


https://github.com/mathLab/PyDMD/


I am going to use DMD to visualize vortex systems in 3D mixing flows.


Maybe also to filter a dominant frequency of a 1D time signal.



How about you?

Thanks for the link to the python code! I see there is not only standard DMD but also several other versions. Great! I use DMD to extract and visualize asynchronous modes in the 2D flow field of a radial fan.
I once tried to do 3D visualization using ParaView, but have not persued it.

Hi Dear, please, I am learned DMD to apply it for my turbomachines, but I still have problems or confused about how to process to geometry into matlab to plot the contours as did in cylinder vortex,
Also do I need to do the post process in tecolot ?
Which or how many code file do I need to write ?
Or could you help me with your codes ?
Thanks in advance
