This is a test recommended by the National Agency for Finite Element Methods and Standards (U.K.): Test 13 from NAFEMS “Selected Benchmarks for Forced Vibration,” R0016, March 1993.
The contour plots were generated by setting the maximum and minimum contour levels close to zero. Where contour levels coincided with the element boundaries, the maximum contour level was increased and the minimum contour level was decreased appropriately.
