Product: Abaqus/CAE
Benefits: You can use the Edit Mesh toolset to insert pore pressure cohesive elements in crack regions, which allows you to model fluid flow into the adjacent material.
Description: At crack regions, you can open pairs of connected elements and insert a layer of pore pressure cohesive elements that are created as orphan elements in the gap region. Inserting cohesive seams is available only in the part context. Using the Edit Mesh toolset, you can select faces (solid cells), element faces (three-dimensional orphan meshes), edges (shells), or element edges (two-dimensional orphan meshes) to identify the crack regions. The region around the crack must be meshed prior to inserting cohesive seams. By default, Abaqus/CAE creates several sets and surfaces to help you make selections in subsequent procedures, such as section assignment.
