Contributions summary:Christina significantly modified the SPECFEM2D code, focusing on implementing Biot poroelastic equations and the adjoint method. Their contributions included adding new files and altering existing ones, particularly `assemble_MPI.F90` and `compute_forces_fluid.f90`, which deal with numerical simulation techniques. They also fixed several bugs related to adjoint source calculations and added capabilities for handling multiple sources and surface waves, demonstrating expertise in computational seismology and wave propagation.
