This model was import as an IFC file into Blender using the ifcopenshell add-on.
The complete model with 1276 elements, was imported into Blender 2.73 successfully. Each element was represented as an individual mesh object. The elements had all triangulated faces which could be in most cases fixed to quad faces for better handling.
By attributing a physically active state and automatic calculation of the concrete masses. The model could then be used in a rough physical simulation. No constraints where applied. The process from importing to the final simulation took ca 5 minutes. The elevator shaft however needed to be taken off because of overlapping geometries.
The simulation does not have any scientific significance, however it is important to point at this procedure, because it illustrates that an external model can indeed directly be used for simulations in Blender.
