LAST UPDATE :February 24th Analytical solution notebook February 22nd 2016 Forward modelling works

ACOUSTIC ADJOINT-STATE RIGOR CHECK WORFLOW

Check this file to know what part is working properly. The notebook contains the symbolic expression for the modelling and inversion of acoustic 2D data. Every loop is written explicitly so the code takes a while to run. The modelling operator are written in symbolic python and the notebook contains text sections explaining the workflow for rigorousness checking of an inversion based implementation.

Intro

All operator have a proper symbolic expression and solvers are setup. Waiting for testing.

The Grid size and time step are based on the CFL condition for a Ricker wavelet with peak frequency f0 (expression commented in the notebook) and the maximum and minimum velocity.

Modelling

Forward/Adjoint modelling in test

Forward modelling behaves properly, shot record has the correct shape. Adjoint test in progress

Inversion

Written, will be updated as the modelling part is tested. It is very low to run as it needs a lot of PDE solves (~10)
