The FFT function (Fourier transform of bore deformation) is supported in TSV-POST.For example, the bore deformation of an engine cylinder block can be expanded easily into Fourier series, to measure the deformation of each order.
Operation can be done very easyly via the GUI, and the automatic interpolation functions provides measure points even if nodes do not exist.

The circularity calculated from each order and its summation is displayed in a graph as shown below.
The sum of the circularity can be calculated practically by eliminating simple expansion or simple moving such as mode 0 or mode 1.
