Meshing Wall/Slab Plates
Meshing Wall/Slab Plates
(OP)
I have created a 3D model of a concrete structure and used plates for walls and slabs. I have had trouble when meshing a wall that is connected to a slab I already meshed. Using the auto mesh tool, Risa does not recognize the existing joints along the common edge and I have to go in and manually adjust joint coordinates so all of the plates are connected. Any advice?
Thanks
Thanks

You have to simply take care as you develop your model to input the meshing to correlate with the previous mesh. This usually means that you have to keep track of the geometrical coordinates of the mesh panels and perhaps input the sections in smaller generations. Then fill in the gaps.
Also, you can use copy or copy-rotate features in RISA to sometimes duplicate mesh panels that have the same nodal rhythm.

Thanks JAE. What sort of mesh size would you recommend? I realized that the plate forces in the spreadsheet are the average values for the plate. So if my plates are large it could be significantly less than the max. at the plate edge.
