For large models, inverting the matrix is highly expensive and will require advanced iterative solvers (over standard direct solvers).
Sometimes, this is also known as the backward Euler integration scheme.
The finite element method (FEM) is a numerical problem-solving methodology commonly used across multiple engineering disciplines for numerous applications such as structural analysis, fluid flow, heat transfer, mass transport, and anything existing as a real-world force.
This practice systematically yields equations and attempts to approximate the values of the unknowns.
In this case, the effect of such a deceleration must be accounted for.
In contrast, when loads are slowly applied onto a structure or surface (i.e., when a monitor is placed onto a table) the loading can be considered ‘quasi-static’ or ‘time-independent’.

You can fix this by pressing 'F12' on your keyboard, Selecting 'Document Mode' and choosing 'standards' (or the latest version listed if standards is not an option).
Inversion of a diagonal matrix is straightforward and includes inversion of the terms on the diagonal only.
Once the accelerations are calculated at the nth step, the velocity at n 1/2 step and displacement at n 1 step are calculated accordingly.
