Products: Abaqus/CFD Abaqus/CAE
Benefits: The ability to define seams in an Abaqus/CFD analysis simplifies the modeling process for fluid-structure interaction analyses involving shells/membranes.
Description: You can now define a seam in an Abaqus/CFD analysis. For an Abaqus/CFD analysis involved in a fluid-structure interaction with shells/membranes, a seam defines a zero-thickness shell in the mesh. You can create a double-sided surface that represents the seam and select that surface as the region for the fluid-structure interaction boundary.
Abaqus/CAE places overlapping duplicate nodes along a seam when the mesh is generated. A seam cannot extend along the boundaries of a part and must be embedded within a face of a two-dimensional part or within a cell of a solid part. Because a seam modifies the mesh, you cannot create a seam on a dependent part instance.
