Examples: tweaked userapi free surface notebook to use MPI-safe implementation

2

Updated this notebook with a better free surface implementation in the vein of Mathias' implementation in the acoustic examples.

[WIP] examples: Add elastic adjoint operator

1

Hi guys, This PR contains the implementations of elastic adjoint equations. The implementation is based on Feng and Schuster (2017): Elastic least-squares reverse time migration (https://doi.org/10.1190/geo2016-0254.1). I hope that you...

If you try to use the absolute value of an index (for example when implementing a free-surface as in the acoustic examples) with a function that is staggered, the staggering...

examples: Boundary reconstruction

Hello everybody. This PR tries to suggest reconstructing the source wave field from the one saved in the border. This should be an option for the gradient computation, in which...

examples: Add a notebook with a toy variable-z topography implementation

3

I made a notebook with a simple implementation of a toy variable-z curvilinear acoustic model with a cosine hill. Still WIP, needs tidy-up and explanations, but lmk your thoughts

cross-loop blocking in staggered tti and *elastic propagators

1

This should improve runtime performance of TTI staggered. The basic infrastructure is already in the codebase (used for example by the CIRE algorithm), but it currently doesn't support the case...

compiler: source injection to nested field

3

Opening for discussion. This helps to work around a bug when injecting to more complex fields such as f(t, u(x,y,z)). Helps to implement Listing 3 of https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=9460483

I propose this issue as a venue to report error messages that weren't helpful in the past, you or that they didn't fit your usecase. This will most likely spawn,...
