In this project the Olympic Tower Munich was tested for its first ten natural eigenfrequencies. The geometry was provided by Filippo Balloni and imported to the SimScale platform. The resulting geometry is shown in the figure below.
The geometry was meshed using parametrized tetrahedralization on SimScale platform. The mesh is shown in the figure below.
The bottom of the tower was fixed in all directions and the simulation was run for first ten eigenfrequencies. The results at mode 1, 3 and 6 can be seen in the figures below.
