A Micro-CT scan of a coarse sand sample was used to generate a mesh for fluid flow simulation. The image data’s resolution was 4.3µm, showing the solid and air domain of the sand sample. High quality tetrahedral meshes were generated for fluid flow simulation.

The soil used in the study was a coarse sand with a mean diameter of 0.55 mm. The image data was segmented within ScanIP using the automated threshold tool. Semi-automated tools such as FloodFill and level set methods can also be used to complete the segmentation.
The segmented data was robustly meshed within minutes using Simpleware’s proprietary +FE Grid meshing algorithm. Matching contacts at interfaces and accurate representation of the domains are guaranteed.
