Magne Sjaastad 55fb8105e2 Do not read NNC geometry out of bounds on INIT and grid file mismatch
transferStaticNNCData() takes the connection count from the INIT file using
ecl_nnc_data_get_size(), but iterates the geometry from the grid file using
ecl_nnc_geometry_iget(). The two counts were only compared in an assert, which
is compiled out in release builds, so an INIT file out of sync with the grid
reads past the end of the geometry vector inside resdata.

Compare the counts at run time, log a warning and iterate the smaller of the
two. Both nncConnections and transmissibilityValuesTemp are filled in the same
loop and stay aligned.

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
