Features

Our core Salvus product consists of five main modules which cover everything required for waveform modelling and inversion:

  • SalvusCompute: Parallel high-performance solver for spectral-element wave propagation on unstructured meshes.
  • SalvusMesh: Library and toolbox to build meshes in both two and three dimensions.
  • SalvusOpt: Non-linear optimization framework.
  • SalvusFlow: Workflow orchestration and remote job execution framework tying together various parts of Salvus.
  • SalvusProject: A high-level user interface and data structure to tie everything together.

We offer these as part of two separate package:

  • SalvusForward
    Includes everything necessary to run highly accurate forward waveform simulations, in two and three dimensions, locally and on remote machines.
  • SalvusComplete
    Everything from the forward analysis package. Additionally unlocks the full power of Salvus by offering everything necessary to run large-scale FWI and other custom workflows.
