Import Results

The Import Results form can be used to import the simulation results after simulating in FLAC3D™. By default, when using the deck as provided by JewelSuite, the simulation results will be in the same folder as the deck, and will consist of several .out files per time step.

To import FLAC3D results

  1. Open the Import Results form.

  2. Select a 3D mesh from the drop-down list. This is typically the same 3D mesh as was used on the Build Deck form, or at least has to be compatible with the results to import (e.g., a copy of the original 3D mesh can be used to import to, but a completely different 3D mesh will not work).

  3. Define a Property folder name. This is the property folder under the 3D mesh in the JewelExplorer to which all properties will be imported.

  4. Select the Deck folder containing the simulation results. This is typically the same folder as the deck folder used when building the deck.

  5. Click Apply or OK. The available simulation results are now imported to the selected 3D mesh and the property folder.

The imported results contain of two parts:

  1. QC properties which have a prefix of '_Initial' These are QC properties (e.g., displacements and stresses) created after the initialization in FLAC3D, before setting the displacements to 0 and starting the real simulation with dynamic results. These can be used to check how much displacement is negated and if there are no severe artifacts due to for example incorrect property definitions.
  2. Output properties of the main simulation When the main simulation has time step information in its pore pressure input (which is typically the case), these will be time stepped properties as well.

After importing the results, they can be further analyzed and post-processed using the available visualization and (geomechanics) tools in JewelSuite.

Some conversions and choices are made based on the imported properties.
  • All imported properties are on element storage type, except the displacements. Conversions between node and element properties are available in the 3D mesh context menu options when needed.
  • Directional information (properties with X, Y, Z in their name) is in the FLAC3D convention. For displacements, JewelSuite automatically creates properties in its own convention (DisplacementE, DisplacementN, DisplacementD) upon import. These appear next to the FLAC3D convention displacements (DisplacementX, DisplacementY, DisplacementZ). Tensors can be converted to the JewelSuite convention using the Convert Tensors tool (model > Geomechanics > Tools > Convert Tensors).
  • All stresses are negated upon import, as FLAC3D follows the engineering convention where compressive stresses are negative, while JewelSuite follows the geological convention where compressive stresses are positive.
  • All imported stresses are total stresses, as JewelSuite typically expects total stress when calculating on properties (e.g., when using Convert Tensors under model > Geomechanics > Tools > Convert Tensors).
  • The choices mentioned above align with the import choices made for Abaqus, as FLAC3D and Abaqus follow very similar conventions.
