Questions about full waveform inversion of elastic waves using JUDI or Devito

[zhangxiaoshuotttt]

HI:

I have recently been experimenting with full-waveform elastic wave inversion using JUDI or Devito. I have been carefully reading your tutorials listed on Devito for the last week (for which I thank you for your hard work).

Today I tried to perform full-waveform elastic wave inversion using Devtio or JUDI. I noticed that in this link, Elastic, there are no AdjointOperator, GradientOperator, or BornOperator, as in the Acoustic .

So the first question I want to ask is, if I want to try the full waveform inversion of the elastic wave, now these AdjoinToperators, GradienToperators have to be written by me, right?

Second, Because I want to read the code written by experts to learn more quickly, so I ask if you have these Operators related to the full waveform inversion of elastic waves at present. If not, I'll write it myself.

Finally, I would like to thank you again for the Tutorials you wrote in Devito and JUDI, they helped me a lot
