AbsDisp

Absolute Displacement

This converger tests the following norm,

$$\left|\mathbf{U}\right|_\infty\leqslant{}tol.$$

where $\mathbf{U}$ denotes the total displacement of the system (with all trial displacement increments accounted). This means

$$\mathbf{U}=\mathbf{U}_n+\sum_{i=1}^{k}\Delta\mathbf{U}^i,$$

where $\mathbf{U}_n$ denotes the converged displacement at the beginning of current sub-step and $\Delta\mathbf{U}^i$ denote all displacement increments/corrections generated by all iterations of the sub-step.
