Read the VTK point data, not only "disp" (now found by name, not position). "pressure" becomes the nodal pore pressure POR, other scalar point arrays keep their name. OPM Flow writes them with --vtk-write-geo-mech-nodal, recovered from its cell values. Stress and strain are cell values in the simulator, so S and E at element-nodal (and integration-point) position give every element corner its cell's value. S is effective stress, tension positive, while OPM writes total stress, compression positive: S = POR * I - stress at each corner, so ST = -S + POR returns the simulator's stress exactly. With S present, populateDerivedResultNames() returns true, so SE, ST, principal stresses, SFI, DSM, FOS, NE etc. are available. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
ResInsight
ResInsight is an open source, cross-platform 3D visualization and post-processing tool for reservoir models and simulations.
Key Features
- 3D Visualization: Grid properties, faults, LGRs, intersections, contour maps and cell filters, using multi-core CPUs for responsive operation
- Ensembles: Grid and summary ensembles with statistics, contour maps and correlation analysis
- Plotting: Summary, well log, RFT, PLT, well allocation, flow characteristics, cross plots and histograms
- Wells and Completions: Well paths, perforations, fishbones, valves and fractures, with export of completion data (COMPDAT, WELSEGS, COMPSEGS)
- Geomechanics: Abaqus results with derived stress and strain quantities
- Seismic: Seismic volumes displayed together with grids and wells
- Model Export: Sector models and grid properties in simulator input format, surfaces as IRAP and TSurf
- Python API: The
ripspackage drives ResInsight and exchanges data through gRPC - GNU Octave: Result manipulation and computations with two-way data exchange
- Cloud Data: Well paths and well logs from OSDU, and grid properties from Sumo
