Architects utilize an iterative design process, making rapid changes to a project based on feedback from all parties involved in a building's lifecycle. And with the growing trend toward collaborative workflows thanks to the rise of Building Information Modeling (BIM), as architects make adjustments to a design their civil and structural engineer counterparts need to react quickly with their own changes to meet shrinking timelines, pushing them to find new ways to boost efficiency. That’s why Nemetschek Scia is introducing Adaptive Mesh Refinement technology for building and infrastructure design.
When engineers receive a architectural model from a designer, they have to convert it to an analysis model and mesh the 2D elements likes walls and shells, as well as lines and nodes. Doing so manually takes up too much time and can drain productivity, especially when you have to conduct a new analysis every time an architect adds, removes, or shifts something in the BIM model. Creating the mesh, testing it, and determining areas of refinement takes up hours of the day and can distract from the completion of the design itself. Scia Engineer software’s Adaptive Meshing simplifies this iterative design process by automatically improving the mesh and adding local refinements. All engineers need to do is input an acceptable error tolerance, a representative load case, and then let the program run.
Making the perfect mesh manually takes a lot of time, and you still won't be able to influence every point, only your chosen refinement zones. And many may not have the knowhow to produce a manual mesh in the short amount of time between when the architect makes a change and when the construction team or the owner needs to see the design. Scia Engineer’s Adaptive Mesh, however, is able to refine every cell individually by comparing Finite Element Analysis (FEA) calculated stress values with theoretically calculated stress/gradient values, allowing engineers to keep pace with designers.
