Typically, when modeling openings in RAM SS that are side by side, users will use the Add Slab Opening - in Bay option, clicking in each bay. With this approach the common edges for the inner wall are automatically removed leaving one larger, merged opening. This is a good practice for most structures, but has one side effect for models that are being integrated with Ram Concept.
When imported to Ram Concept, the larger opening prevents any slab from remaining along the center wall:
And this leads to wall meshing errors like this:
As well as an instability since the wall inside the opening can now fall over out of plane.
The error can be fixed directly in Ram Concept by adding a sliver of slab (or a beam) along the wall from one side of the opening to the other. Alternatively, the errors can be prevented by modeling two distinct openings in RAM SS from the beginning.
This is one case where using construction grids and 0" overhang slab opening edges is advised. The resulting Concept model will also have 2 distinct openings and the wall in the middle will be OK.
