I have done mesh repair jobs in Rhino to remove naked and non-manifold edges as well as filling gaps,,,etc. In Abaqus/Standard the default output points through the thickness of a shell section are the points that are on the bottom and top surfaces of the shell section (for integration with Simpson's rule) or the points that are closest to the bottom and top surfaces (for Gauss quadrature). From the main menu bar, select Shape Shell Extrude. Similarly, a mesh part is created in the Mesh module or imported from an output database as the base feature of a new part. You model a two-dimensional planar part using two-dimensional solid continuum elements, as well as truss or beam elements. 3.
