Nonlinear dynamics and time-integration

Question asked by Erik Kostson on Nov 2, 2018

In SW 2017, under nonlinear dynamic analysis and their properties (advanced settings), there are three options for the integration (drop list). One of them is the so called central difference which when I have implemented something similar refers (at least for me) to an explicit scheme. (It would not be strange, because in the SW help, it says that the drop test module uses an explicit scheme)


Unfortunately I can not find anything about it in the SW help (only about Newmark and Wilson implicit schemes), thus I am asking for some help.


Many thanks
