This is a bugfix release which addresses the following issues:

Wavefront tracer

  • Handle rare cases in anisotropic models where numerical instability causes  travel time computations to collapse and output faulty travel times.

Distributed machine setup

  • Added a consistency check on remote machines to enable a quick fix if remote machines point to a different version of the software than the front-end machine.

It will work for homogenous systems with standard setup.

Kirchhoff Prestack Modelling Workflow

  • Improved scalability on job distribution
  • More efficient cleanup in final merge task
  • Fixed a bug in resource probing when recovering a failed workflow run

Note: Failed or canceled workflows, which have been run with older NSS versions, must not be recovered. Require full re-run.

Kirchhoff Target Migration Workflow

  • Fixed bug in computing target bounds from Kirchhoff prestack target model if no sub-area was selected.
  • Improved scalability on job distribution.
  • More efficient cleanup in final merge task.

Note: Failed or canceled workflows, which have been run with older NSS versions, must not be recovered. Require full re-run.

License handling of sub-processes

  • More efficient license checking to avoid license server crash on heavily parallelized workflows.

Project selection

  • When entering a path in the project directory field of the main window, a project selector pops up if the path is not a valid project.

Common Shot Tracer – Travel time cube workflow

  • Fixed problem with shot index in SEGY export of travel time cubes.
  • Archiving: Include shot index information.

Property operations (object list)

Unit conversion error in "Extrapolate distance" field.

Time-Depth conversion of grid surfaces

Fixed handling of undefined positions.
