Low order elastic wave equation

1

First order Spectral Element Method (SEM) for the second order elastic wave equation. In this PR we propose the first version of the elastic wave solver using the SEM. The...

Elastic Vertical Transverse Isotropic (VTI) wave solver implementation

1

In this PR, we add the Elastic VTI physic for the second order wave solver. The main difference between this one and the isotropic case (ElasticWaveEquationSEM.cpp) is the elasticity tensor...

Enable high order for fwi in acoustic wave solver

1

This PR generalize the formula for gradient computation inside the acoustic second order wave solver to high orders The main change is the computation of the number of nodes per...

2

This PR add the call to free some array from GPU memory using freeOnDevice method added in the following LvArray PR : https://github.com/GEOS-DEV/LvArray/pull/298

feat: Add option for automatic timestep computation in wave solvers

2

This PR add the possibility of compute automatically the timestep for wave propagation solvers. How to use it? - You add the correct switch in your `XML` (`timestepStabilityLimit`=1) - You...

Refactoring wave solver: new folder organization

1

This PR is the final part of the refactoring for wave solvers It mainly contains new folder organisation + small cleanup

feat: Add Taper Layers in wave solvers

1

This PR add a first version of Taper layers for wave solvers These layers are set to improve the efficiency of absoption of boundaries. This is how the version version...
