The updating is mainly to reduce the descripancy between experimental and numerical modal frequency
i think its better to use Ms-Exel
@Abu Hashan Md Mashud. I haven't used Excel for Finite element updating. Are you able to shed more light please
I suggest you to follow https://arxiv.org/pdf/1602.08137.pdf
