Export to Abaqus Formats

ExportGeo-Abaqus

The ExportGeo-Abaqus module acts as a seamless interface between GeoDict and Abaqus, enabling the export of structural models generated with modules like FiberGeo or CT scans imported via ImportGeo-VOL. The export incorporates all the necessary computational settings required for the Abaqus FEM solver.

ExportGeo-Abaqus is particularly valuable for Abaqus users who find CT scan preprocessing challenging or seek to utilize GeoDict's advanced geometrical material models within Abaqus. The module supports exporting both volume elements (for any 3D scan or GeoDict model) and beam elements (for fibrous materials and open-cell foams). For exporting beam elements from a fibrous material based on a CT scan, prior analysis with the FiberFind module is required. Additionally, ExportGeo-Abaqus automatically includes boundary nodes and conditions, eliminating the need for manual adjustments and streamlining the workflow.

In our experience, GeoDict with FiberFind-AI is the most powerful software for generating precise FE models for Abaqus from µCT scans.Transferring nonwoven data into highly accurate fibre models for deformation simulations is a matter of minutes, not hours or days!

ExportGeo-Abaqus Features

The ExportGeo-Abaqus module offers two options for exporting material models:

  • Export Stiffness Simulation (Voxel): This feature exports voxelized data as an unstructured volume mesh (*.msh) and an Abaqus input file (.inp) for elasticity computations in Abaqus. The Abaqus input files are saved in ASCII format, allowing easy modification in any text editor if needed. To run the exported simulation, simply execute the *.inp file in Abaqus.
  • Export Fibers as Beam Elements: This powerful feature enables the export of complex fibrous materials and foams as beam elements, allowing for highly detailed yet efficient simulations in Abaqus. The exported file is again an Abaqus input file (*.inp), ready for direct execution in Abaqus.
