Chao_Jiang Hi, I'd like to invert B by observed velocity and modeled velocity from transient simulation. May I know how to implement that?
mathieumorlighem In other words, you would like to do a Transient Calibration, and not a snapshot inversion (see https://tc.copernicus.org/articles/9/2429/2015/)? If that's the case it requires Automatic Differentiation and it is not fully supported yet (it works but it require a lot more code and we have not developed any tutorials yet) Cheers Mathieu
