    • Allow now to keep the gray-value geometry information during the deformation with "On Deformed Geometry" to get a better results for the updated geometries.
    • All the geometry related options are moved to a separate tab in the ElastoDict dialog.

    • efficiency plot (for filter media).
  • The particles color of a filtration simulation can be set according to the batch ID (color is interpolated between blue and red).

  • Show relevant equations and references in the corresponding tab in the AddiDict dialog.
  • Additional choices of the flow boundary conditions e.g. "symmetric".

SatuDict:

  • Three new predefined script are available in SatuDict for forced imbibition:

    • Forced Imbibition - Load Structure.py: This script adjusts material IDs and material colors to ForcedImbibition script defaults upon loading geometries (*.gdt).
  • Speedup of about 20-30% for SatuDict, depending on mode/structure (for the whole SatuDict execution).
  • The pore radius shown in the capillary pressure report is now changed to diameter.
  • The Thomeer fit model can now be computed on mercury intrusion capillary pressure simulations (or drainage experiment without residual phase).
    • The Thomeer fit consists of three model parameters: unresolved (or hidden) porosity, displacement pressure, and the pore geometrical shape factor.
    • The fit parameters are shown in the capillary pressure report as table and the curve is shown in the plot section in addition to the computed capillary pressure curve.
  • The capillary pressure post-processing now has an invert check-box that allows to invert the saturation axis in the plots

PoroDict & MatDict:

  • In "MatDict" for "2D Density Map" the resulting 2D map is also saved in the *.gdr file result map (before it was only saved in the plot).
  • Allow to compute a more accurate "Geodesic Tortuosity" with the option "Optimize Paths". This adds a post-processing step removing the stair-case pattern artifacts in the paths and thus leads to more accurate results.
  • Allow to compute a more accurate "Percolation Path" with the option "Optimize Path". This adds a post-processing step removing the stair-case pattern artifacts in the paths and thus leads to more accurate results.
  • Improved the algorithm for 1D Statistics. The post-processing allows now the re-computation with different methods.

  • In the database, "Predict Compression" only works correctly for materials within a ceratin permeability range. This range has now been enlarged by two orders of magnitude.
