معنی relaxation در این متن مربوط به حل معادله در مسائل نشت در رشته عمران

Relaxation method. The relaxation method is one of the solution methods for finite difference equations which is the most suited to spreadsheet calculations. In the relaxation method, the unknowns are initially assigned an arbitrary value, Then new values are calculated from old ones by iteratively using Eq. 28 until their final values satisfy Eq. 28 within a specified error tolerance.

For instance, the problem of ,Fig. 8 can be solved by relaxation as shown in Figs. 9 and 10.
