ExportGeo-Abaqus

Export to Abaqus (ExportGeo-Abaqus) convert voxelized data to formats for elasticity computations with Abaqus. The .inp files are saved as ASCII files so that, if changes are required, they can be opened and edited with a text editor.

Based on the voxel structure, GeoDict also generates an unstructured volume mesh (.msh file), as needed for Abaqus.

Access ExportGeo-Abaqus by selecting Export ExportGeo-Abaqus in the menu bar.

Learn to use ExportGeo-Abaqus

  • Export Stiffness Simulation (Voxel)
    With Export Stiffness Simulation (Voxel), the current voxel structure is exported and the parameters for simulations to compute the stiffness tensor are automatically set up for Abaqus. For this, the supported Abaqus versions are Abaqus 6.9 or newer. Additionally, all necessary simulations for computing the effective stiffness tensor are defined. This includes simulations for 6 different load cases.
  • Export Fibers as Beam Elements
    With Export Fibers as Beam Elements, fibers from a GeoDict structure (e.g. created with FiberGeo) are exported as beam elements for Abaqus simulations.

Note-Important

Important! Abaqus elasticity computations are accurate but require high amounts of memory and are generally highly time-consuming.

The same accurate results can be achieved with the ElastoDict module directly in GeoDict. Find the details about how to set calculations of Effective Stiffness (FeelMath-VOX) in the ElastoDict User Guides.

In general, this is the recommended way to proceed if ElastoDict is present in the GeoDict license. Since the FeelMath solver is optimized for voxel structures, the computations are faster and more memory efficient and, therefore, ElastoDict can handle much larger data sets than Abaqus.
