ResInsight can be built with support for reading and displaying geomechanical analysis models produced by ABAQUS in the *.odb format. This is only possible if you or your organization has a copy of the ODB-Api from Simulia, and a valid license to use it.

If you have, and would like to a use these features, please see Build Instructions for a description on how to build ResInsight and how to include the support for odb-files.

Geo Mechanical Data Support

Geo-mechanical data can be imported using the Import -> Geo Mechanical Cases menu. Here two options are present: Import Geo Mechanical Model (odb files) and Import Element Property Table.

ResInsight supports the elements C3D8R, C3D8 and C3D8P which are all HEX8 cells. It is also assumed that there are no other element topologies present in the odb file, and that there are only one part. For IJK-based range filters to work, it is also assumed that the elements in the part is topologically arranged as a complete box.

ResInsight loads the second frame within each odb-step, and present those as the time series for each result.

All the result fields in the odb-file is then available for post processing in ResInsight, but stresses and strains are converted to pressure-positive tensors as normally used in geomechanics, instead of the normal tension-positive tensors that ABAQUS stores.

Pressure and stress are always displayed using the Bar unit.

Other derived results are also calculated, and are described in Derived Results

ResInsight Features

Most of the central features of ResInsight visualization setup also applies to ABAQUS Odb models, like range filters and property filters. Well Paths will also show up along with the odb models.

The Octave interface, however, does not support the odb-data yet.
