RelError

Relative Error

This converger tests the following ratio,

$${\displaystyle \frac{{\left|\mathbf{E}\right|}_{\mathrm{\infty }}}{{\left|\mathbf{U}\right|}_{\mathrm{\infty }}}}⩽tol.$$

where $\mathbf{E}$ denotes the error vector set by other solvers, etc., and $\mathbf{U}$ denotes the total displacement of the system.
