Absolute Acceleration Increment

In the governing equation,

\[ \mathbf{M\cdot\Delta{}A=R}, \]

this converger tests the norm of displacement increment, viz.,

\[ \left|\mathbf{\Delta{}A}\right|_\infty\leqslant{}tol. \]

The equation of motion based on acceleration is conventionally the governing equation in explicit analysis.
