NORSAR Software Suite 2021.2 is a major new release featuring new tools and several improvements and bug fixes.

The new Workflow Queue System allows the user to set up and run a queue of workflows e.g., several batch wavefront tracer setups, or a number of different illumination maps. It is an efficient tool for generating different modelling results for example by running the queue automatically over night.

The Illumination Cubes workflow is a new NORSAR-3D workflow that can be used e. g. as a survey planning device in connection with surveys intended to be used for inversion projects (tomography, FWI etc.). The workflow performs tracing through the model and maps the ray paths to a regular 3D cell grid in space. Several ray attributes can be mapped, in order to get a picture of to what extent the parts of the model are penetrated (illuminated) by the rays, and what ray directions are represented.

A 2D model can now be extracted from a 3D model along a 2D New General Section in the NSS project (in addition to a 2D model along an Inline/Crossline Section). The general (random) section is along a selected NSS polyline. The NSS 2D modelling allows for a user-friendly and efficient ray-path and event analysis, even in the most complex models.

A 3D model from a set of NORSAR-2D models is introduced. The 3D model is approximately interpolating between the 2D models. The selected models may be inlines or crosslines or a combination of inline and crossline or general sections. All selected models must have the same number of surfaces.
