AD.2005.1.3 Wall-slab Interface Considerations in Finite Element Meshing
In the plate element mesh generation for a panel type of entity like a wall or slab, STAAD.Pro now provides a facility for the consideration of boundary conditions at the interface of the panel and any other panel on whose surface one of its edge lies.
To illustrate the problem that one faces if the facility did not exist, consider the wall and slab shown in the figure below:
The Parametric Models facility may be used to mesh the slab, and use the wall boundary as a density line, resulting in the following mesh for the slab.
If the wall is to be meshed subsequently, the nodes along its common boundary with the slab, as shown in the above figure, must automatically be "control points" in the wall meshing process. There was no simple way to do this until now.
