Kristian Bendiksen 0ad61a004a #14345 Grid Calculation: replace undefined values with default value in aggregations
Aggregation functions like sum() in the expression parser include all
values in the input vector. Undefined values (HUGE_VAL) could leak into
the aggregation input when a grid case group member has fewer time steps
on disk than the main case it inherits result meta data from, or when a
cell is active in the calculation case but has no value in the source
data. This produced infinite sums for some realizations, while the
histogram statistics ignore undefined values.

Replace undefined values in the aggregation input with the default value
0.0, matching the histogram semantics, and log a warning per case and
variable when values were replaced.

ResInsight

ResInsight is an open source, cross-platform 3D visualization and post-processing tool for reservoir models and simulations.

Key Features

  • Specialized Visualizations: Tailored for efficient interpretation of reservoir simulation data with visualizations of properties, faults, and wells
  • Performance-Oriented: Exploits multi-core CPUs and GPUs for highly responsive operation
  • Statistical Analysis: Handles large numbers of realizations with built-in statistical calculations
  • Python Integration: Enables powerful result manipulation and computations with two-way data exchange
  • GNU Octave Integration: Enables powerful result manipulation and computations with two-way data exchange
  • Extensible Framework: Supports additional data sources and visualization methods (solvers, seismic data, CSEM, geomechanics)
  • Eclipse Integration: Supports export to Eclipse input formats for simulation cycles and parameter studies

Supported Input Formats

  • Eclipse binary output (*.GRID, *.EGRID files with corresponding *.INIT, *.XNNN, and *.UNRST files)
  • Selected Eclipse input file sections
  • Grid information with cell property data sets

Technology Stack

ResInsight utilizes:

  • Equinor/resdata and OPM/opm-common libraries for Eclipse result file access
  • Qt for the application framework
  • Qwt for plotting functionality
  • vcpkg for dependency management

Platform Support

ResInsight is cross-platform with automated testing on:

  • Red Hat Enterprise Linux (RHEL)
  • Ubuntu
  • Windows 11

Documentation

Development

Source Code

git clone git://github.com/OPM/ResInsight.git

Minimum Requirements

  • gcc 13
  • clang 19
  • CMake 3.15
  • MSVC 2022 17.4

These requirements are defined by used features in c++23 like std::stacktrace and std::expected.

Dependencies

Most dependencies are managed using vcpkg as defined in vcpkg.json
