Feature Matrix

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 three separate package, ranging from least to most features:
  • SalvusForward
  • SalvusSensitivity
  • SalvusComplete

SalvusForward

Includes everything necessary to run highly accurate forward waveform simulations, in two and three dimensions, locally and on remote machines.

SalvusSensitivity

Everything from the forward modeling package. Additionally includes the ability to compute gradients and use these for linear RTM.

SalvusComplete

Everything from the sensitivity analysis package. Additionally unlocks the full power of Salvus by offering everything necessary to run large-scale FWI and other custom workflows.
