Line 6: It is also possible to test a physical object to determine its natural frequencies and mode shapes. This is called an [[modal analysis\|Experimental Modal Analysis]]. The results of the physical test can be used to calibrate a finite element model to determine if the underlying assumptions made were correct (for example, correct material properties and boundary conditions were used). == FEA eigensystems{{Technical inline\|date=September 2024\|reason='FEA' has not been defined or mentioned elsewhere in this article}} == ~~== FEA eigensystems ==~~ For the most basic problem involving a linear elastic material which obeys [[Hooke's Law]],
